4.  Administrivia
  a. Any last minute FTF logistical questions?

No telcon next Thursday
No telcon on Thanksgiving (28th)

5.  FTF agenda [.1].
    Besides the current discussion topics, we should have time to go over some open issues.  Here are a set of candidates I came up with from the issues list at [.2].  Champions appreciated!

We'll have time for some issues - could we get some champions? (no, not Mike)

Type system issues:
    Allow non-XML type systems?    
      (this is related to the schema-to-wrap-other-systems 

    Clarify use of type= and element= in part with XML Schema experts.
      Jonathan: Looking for a volunteer to clarify this
      Arthur steps up [Arthur: concerning the type vs element issue, 
      see Why <part element=...> Should be Dropped] [.3]

Naming issues:
    Need to be able to distinguish between operations with the same 
    NCName in different portTypes    
    Should faults be named with QNames?    
    Should all top-level elements' names be unique across the 
    target namespace?    
There are advocates for these issues (David, Philippe)

Part 2 issues:
  Are there any issues we can tackle prior to the property/feature discussion?

None identified.

[Philippe: Arthur will not participate on Wednesday, JJM not on Monday. Sanjiva may drop by on Tuesday.]

[.3] http://lists.w3.org/Archives/Public/www-ws-desc/2002Sep/0055.html

6.  New Issues.  Merged issues list [.1].
      None found.

[.1] http://www.w3.org/2002/ws/desc/2/06/issues.html

7.  Managing extensions [.1].  Is a registry called for?  Philippe's summary of a related issue in WS Arch [.2], about WS-Security defining WSDL extensions [.3].  

(conversation about OASIS WS-Security TC, WSDL extensions, and which versions of which specs they're using)
Jonathan: Is this something we need to take a position on / deal with?
[dbooth: Here is David Orchard's draft message to OASIS WS-Security TC: [.3]]
Philippe: don't need to think about it until TC responds.
Jonathan: All we need is a statement that we're not currently working on extensions?
Joyce: if we have this in the email threads, that's enough

Do we want to participate in the arch group's statement to the TC?
Consensus: We just need to know about it, don't need to do anything else for now.

[.3] http://lists.w3.org/Archives/Public/www-ws-arch/2002Nov/0006.html 

8.  WSDL media type registration.  Mark Baker's conclusion [.1]. Tag finding [.2], WG process guideline [.3].

conversation: We define a vocabulary, so we should follow the TAG finding and define a media type.
[Philippe: application/soap+xml: [.4]]
(discussion of limitation of "text" types being limited to US-ASCII or not)
Need someone to look into the "urban myth"ness of the limitation
[Philippe: if a text/xml entity is received with]
[Philippe: the charset parameter omitted, MIME processors and XML processors]
[DaleMober: from rfc 2046 text -- textual information. The subtype "plain" in particular indicates plain text containing no formatting commands or directives of any sort. Plain text is intended to be displayed "as-is". No special software is required to get the full meaning of the text, aside from support for the indicated character set. Other subtypes are to be used for enriched text in forms where application software may enhance the appearance of the te]
[Philippe: MUST use the default charset value of "us-ascii". [.5]]
Jonathan: we could just agree to do a media-type, either as an appendix or a separate spec, and describe there the issue of how to deal with text/application tension
JJM: No normative text in the IDraft anymore for SOAP1.2, pointer to SOAP appendix
[alewis: RFC 3023 appears to discuss all of the relevant issues surrounding the use of text/xml versus application/xml (and correspondingly application/xyzzy+xml). Issues are that text/xml defaults to US-ASCII, although the charset parameter is recommended to be UTF-8, which is supported. UTF-16 cannot be supported as a charset, it appears.]
[DaleMober: Whoever registers wsdl type should check [.6] section 7.1 through 8.x]
