mm1: Thanks for forwarding this Diane and sorry for a delay in 
responding (as noted, limited access). Comments and suggestions below:

General: Several of these issues touch on the dependent functions: state 
management, compensation and activity structure.  Therefore, we may, 
even if substantial, address them in a compiled fashion to understand 
the breadth of the issues and to get a balanced resolution. RE: 
1,2,3,5,6 etc. for example.

    * Defer this type of prioritization not based on function but
      complexity. Whether or not the issue will be addressed within the
      scope of the effort will be decided by the TC.  Agree with Goland
      that this is subjective at best and should not be used as a
      criteria.  Other than if the TC feels the impact of the issue is
      in/out of scope (and important to the specification and adoption).
    * *I would suggest we consider what broad function areas are
      important such as: (1) state management and correlation, (2)
      asynchronous type operations, compensation and fault handling,
      supporting WSDL and XML, and (3) other such as editorial.  *Here
      are a few examples of why I propose this:
          o On an XML 'group', although some of these items do touch on
            XML, the central items of concern surround correlation.  We
            should concentrate on the functional issue and address that
            and ensure that the XML is supportive or robust enough to
            handle the functional area. RE: 11, 29, 39, 46, etc. for
            example.
          o Functions that may support asynchronous operations or
            long-running transactions may support capabilities outside
            of the scope of BPEL.  We need to resolve how to prioritize
            and if the references to WS-Transaction are considered
            normative.  Please advise.
          o Suggest we address WSDL and XML together - technology
            related constraints or parameters in order to ensure we use
            their capabilities and either technology where most
            appropriate.  These may not be independent. RE: 7, 12, 13, etc.
          o Suggest we address event handling per the functional areas
            supports such as the alarm handlers raised by Jeyaraman. 
            For example, 32 is tied to correlation and assessing it
            independently may not address the issues.
          o Error handling is key to several functional areas not just
            compensation. This should be addressed in general as it
            relates to lower level SOAP faults (if applicable), in
            support of events, activities, etc.

Issue 1: Although implications could be significant, this is an 
important issue for compensation (and to some extent other functions in 
the specification).
Issue 2, 6: Although these are deemed significant issues they are 
important to the specification's robustness and suggest these be 
considered.  Significant
issues should be addressed carefully because any deferral may impact 
specification viability.
Issue 26: The actual meaning / use of <sequence> and <flow> impacts this 
issue. And further discussion was initiated on related issues on the 
list.  This
should be addressed in a group. RE: 22, 23, 26, etc.

I've provided a broad matrix with color codes (in StarOffice/OpenOffice 
version) to show the larger potential buckets where these issues fall. 
Note, there are several categories that may apply to an issue but I have 
only provided a suggested primary one. These do not differ significantly 
from the submitters, but takes a more functional approach on key areas 
of interest.

Thanks.
