Proposed DSML 2 schema changes

[Jeff Parham <jeffparh@windows.microsoft.com>]

Title: Message

The attached is a strawman including the following proposed changes:

• Adds the model attribute to the DSMLEnvelopeRequest element (see below).
• Fixes a typo in the LDAPErrorCode enumeration.
• Adds controls to the LDAPResult element.  The LDAPResult element is used as the response type for all operations other than searches and extended requests, and per RFC 2251 all responses can contain controls.
• Incorporates the requestID proposed by John McGarvey (IBM) and Christine Tomlinson (Sun).  The only change from Christine's representation is that the requestID is an attribute rather than a child element.  Incorporated John's suggestion that the requestID can occur on envelopes as well as individual requests/operations.
• Changes oc-class from minOccurs=1 to minOccurs=0.  This allows for DSML transformations of LDAP search responses corresponding to search requests in which typesOnly=true.
• Removes the dn attribute from ExtendedResponse.  (There is no such field in RFC 2251's ExtendedResponse.)

The proposed model attribute of the DSMLEnvelopeRequest has two possible values -- sync and async.  The sync value indicates that the responses corresponding to all requests in the envelope must be bundled into a single DSMLEnvelopeResponse -- i.e., the behavior described in the original MS proposal.  The async value indicates that the responses corresponding to each request in the envelope may be sent asynchronously (using multiple DSMLEnvelopeResponse elements if needed).

 

In addition I propose that the specification document state the following:

• A DSML implementation MUST support model=sync or model=async.
• A DSML implementation MAY support both model=sync and model=async.
• A DSML implementation MAY support mutliple operations per DSMLEnvelopeRequest.
• A DSML implementation MAY support multiple responses per DSMLEnvelopeResponse.

For example, this would grant Microsoft the flexibility of not supporting the async model and iPlanet the flexibility of not supporting batched operations.
