Subject: [legalxml-ms] OASIS TC Call for Participation: LegalXML Legal Intercept

A new OASIS technical committee is being formed under the LegalXML 
member section. The OASIS Lawful Intercept Technical Committee (LI-XML 
TC) has been proposed by the following members of OASIS: Anthony M. 
Rutkowski, VeriSign; and the following individual members: John Messing 
and Daniel J. Greenwood.

The proposal for a new TC meets the requirements of the OASIS TC Process 
(see http://oasis-open.org/committees/process.shtml), and is appended to 
this message. The proposal, which includes a statement of purpose, list 
of deliverables, and proposed schedule, will constitute the TC's 
charter. The TC Process allows these items to be clarified (revised) by 
the TC members; such clarifications (revisions), as well as submissions 
of technology for consideration by the TC and the beginning of technical 
discussions, may occur no sooner than the TC's first meeting.

To become a member of this new TC you must 1) be an employee of an OASIS
member organization or an Individual member of OASIS; 2) notify the TC
chair, Anthony M. Rutkowski (tony@verisign.com) of your intent to
participate at least 15 days prior to the first meeting; and 3) attend
the first meeting on 6 January. You should also subscribe to the TC's
mail list. Note that membership in OASIS TCs is by individual, and not
by organization. You must be eligible for participation at the time you
time you notify the chair.

The private mail list legalxml-intercept@lists.oasis-open.org is for
committee discussions. TC members as well as any other interested OASIS
members should subscribe to the list by going to the mail list web page
at http://lists.oasis-open.org/ob/adm.pl, or by sending a message to
legalxml-intercept-request@lists.oasis-open.org with the word
"subscribe" as the body of the message. (Note that subscribing to the
mail list does not make you a member of the TC; to become a member you
must contact the TC chair and attend the first meeting as described in
the preceeding paragraph.)

A public comment list will be available for the public to make comments 
on the work of this TC; a message may be sent to the TC via the address 

The archives of both of these mail lists are visible to the public at

OASIS LegalXML Lawful Intercept (LI-XML) TC Charter

1. Name of Technical Committee

The name of the committee is the Lawful Intercept XML (LI-XML) Technical 
Committee (TC) within the LegalXML Member Section of OASIS. The 
Technical Committee may constitute subcommittees or other groupings as 
necessary and appropriate to carrying out the Technical Committee's purpose.

2. Purpose of the Technical Committee

A. Mission

The LI-XML Technical Committee exists to produce a structured, 
end-to-end LegalXML Lawful Interception Process framework consisting of 
XML standards and authentication mechanisms, including the development 
and harmonization of identifiable related XML standards and XML 
translations of ASN.1 modules, including proprietary ones made available 
in accordance with IPR policies.

B. Language and Applicable Legal Domain

The scope of the LI-XML TC will be focused upon lawful interception 
processes and documents worldwide.  This will include both national 
andlocal levels, although this is dependent on the level of 
participation by country practitioners.  In the USA, the dual levels 
include federal and state legal domains.  Global LI requirements, 
specifications and standards developed and maintained by the European 
Telecommunications Standards Institute (ETSI) will be considered through 
a liaison process with the ETSI Lawful Intercept Technical Committee (TC 
LI). It is expected that the LI-XML TC will assume English and 
eventually other languages.

C. Scope

The core scope of this activity is the creation of standard 
schema(s)/DTDs that can be used by parties in all stages of the lawful 
interception process.  See - Lawful Intercept Process Model, 

The Lawful Interception process herein described consists of a set of 
interrelated actions taken by law enforcement or national security 
agencies (LEAs), judicial authorities, and telecommunication and 
information system providers or their agents that result in the 
discovery and production of investigative or evidentiary records 
associated with network-based communications capabilities and uses to a 
Law Enforcement Monitoring Facility (LEMF). The process is effected in 
nearly every country pursuant to national, local or intergovernmental law.

This investigative process typically has as many as four iterations to 
obtain: a) customer and service provider reference information; b) 
customer historical communications records; c) real-time Intercept 
Related Information (also called communications or call-identifying 
information); and d) real-time communications content.

Each of these iterations consists of actions and objects in as many as 
five stages - depending on the law of the jurisdiction(s) involved. 
Usually the judicial administrative and review process becomes more 
extensive as privacy considerations come into play.  Subpoenas are 
generally required for customer historical records; and judicial 
warrants or orders are the norm for real-time information.

The four stages consist of 1) an initiating Law Enforcement Agency 
making application to a judicial or administrative body, which in turn 
2) issues an authorizing instrument for 3) execution by the party or 
parties or their agents to 4) obtain the required information through 
some kind of a technical or administrative mechanism, and 5) handover to
a recipient Law Enforcement Monitoring Facility.

At the entry and exit point of each stage, there is additional set of 
actions that consists of the authentication of the parties, secure 
transfer of the information object with time stamps and receipts, 
verification of the content, implementation processing, and the 
generation of an associated a secure audit log.

If emergency or exigent conditions exist, the second stage of the 
process (judicial issuance of an authorizing instrument) can usually be 
altered by the LEA using another instrument coupled with a posteriori 
judicial or administrative action.

The LI-XML TC shall also consider tagged database resources that provide 
for the effective authentication of all parties in the lawful intercept 
process that include LEAs, judicial or administrative authorities, 
communication systems providers and their agents.

Other OASIS LegalXML activities are relevant, especially SAML, WS 
Security, Electronic Court Filing, eNotarization, and Integrated Justice 
  TCs.  Compatibility and use of existing schema will be attempted where 

To support this scope, the LI-XML TC shall seek to identify and capture 
other XML schemas/DTDs in-use or under development, as well as 
frameworks and  LI-related ASN.1 modules developed by standards bodies 
and national authorities.  See Lawful Intercept - Existing Global 
Models, http://www.gliif.org/images/LI global_models.htm.  Toward this 
end, introduction of this activity was favourably discussed with 
theLawful Intercept Technical Committee of the ETSI at its recent 
Plenary Meeting, Dublin, 15-17 Oct 2002, and national LEA 
representatives present.

3. Requirements Definition

The LI-XML TC will conduct a comprehensive verification of the following 
initial requirements:

- XML compliant syntax used for representing the LI process and 
associated documents.

- W3C and OASIS specifications, as well as, ISO or other appropriate 
standards shall be used except in those cases made impossible by the 
legal and binding adoption of non-standard, but legal requirements 
including and especially relating to laws that protect parties to the LI 
process and the public.

- A set of LI-XML Components that can be used universally by all LI 
Schema(s). These component specifications may include elements and 
attributes (e.g. unique identifiers, creation dates, etc.), as appropriate.

The solution will allow efficient management of the Life Cycle of LI 
documents, from creation of an LI application instrument to the archival 
of target records.

4. Deliverables and Schedule

    4.1  Global LI-XML process framework XML Schema that can represent 
all discoverable LI processes.  20 Jan 2003

    4.2  Identify and provide a means of discovering on a continuing 
basis, all LI related XML schemas ASN.1 modules.  This will be done in 
collaboration with ETSI TC LI and relevant national standards bodies and 
authorities.  20 Jan 2003

    4.3  XML Schema(s) for LI processes specified in this Charter and 
deriving from the framework.  This may be done, in part, with the 
LegalXML Court Filing and Integrated Justice TCs.  Technologies from 
other existing OASIS TCs such as SAML and WS Security will be used. 1 
Aug 2003

    4.4  Provide for a common global means of authenticating parties, 
schemas, and transport security associated with the LI process.  This 
may be done in cooperation with the LegalXML eNotarization TC.  1 Aug 2003

    4.5  Create "data dictionaries" which provides the intended meaning 
of each element, attribute or other component of the final specification 
with the a means of simple translation to languages other than English. 
1 Sep 2003

    4.6  Create standard XML Encoding Rules (XER) for significant ASN.1 
LI modules in coordination with the relevant sponsoring body or company 
(if proprietary).  1 Sep 2003

results.  31 Oct 2003

5. Language in which the Technical Committee will conduct business

All business will be conducted in English.

6. Working Methods

The Technical Committee will follow the operating rules of OASIS and any 
operating rules adopted by the LegalXML Member Section Steering 
Committee with the approval of OASIS management and the OASIS Board of 
Directors. In addition, the Technical Committee will abide by the 
following practices:

    1.  All decisions will be made by consensus.

    2.  All decisions made in face-to-face meetings will be subject to 
ratification or rejection by the full membership of the Technical 
Committee on the list serve.

    3.  All email discussions concerning the technical work of the 
Technical Committee and its subcommittees will take place on OASIS 
supported list serves.

    4.  One member of the Technical Committee and of each subcommittee 
will serve as ombudsman to monitor the public list for that entity and 
provide input from the public list to the committee and subcommittee 

7. Intellectual Property

In no event shall this Technical Committee finalize or approve any 
technical specification if it believes that the use, distribution, or 
implementation of such specification would necessarily require the 
unauthorized infringement of any third party rights known to the 
technical committee, and such third party has not agreed to provide 
necessary license rights on perpetual, royalty-free, non-discriminatory 

8. Formation Information

The first meeting will be held by phone on 6 January 2003.
