		JeffM: Concern that additional participants could bias towards
		a company that added these people vs. one that didn't.
		JohnM: Process doesn't allow invited experts from member 			companies.
		
		Group Discussion:
		Discussed ways to include additional people (task force etc.)
		XMLP Group added people for testing specific tasks. 				(Soapbuilders)...(how)?

		submitting test cases etc. to the W3C.

------------------------------------------------------------------
10. Issue 85: HTTP binding options [.1]
- option 1: drop HTTP binding
- option 2: input becomes POST body and output is POST response
- option 3: option 2 + GET goes to http:address URL and output is
GET response
- option 4: option 3 + rules to move all parameters into query
parameters for GET binding with MEP=in-out and
@style=rpc
- option 5: option 4 + URL replacement (not just query params)
Continue thread from previous weeks.

		Discussion:
		JohnM: Current group thoughts look somewhere between
		Option 3 and Option 4.
		
		Sanjiva and Philippe:
		Discussed how a message/elements would be "divided" between
		URL, query params. (What would the rules be...?)
		
		Jacek: against splitting message elements. message
		should be contained in the body.

		Arthur: no harm in duplicate info in URI if helps addressing.
		Umit: agrees w/ Jacek 

		Long discussion about splitting of information.
		Generally agreed that query params are ok as long as the
		payload contains the complete set.
		Question about messages that could be completely represented
		in the URI/URL. (Still a need to have duplicate info. in the 		body??)

		
		Resolution: none that the scribe could detect...:) 


		New Action Item

		Philippe: will write/update proposal and post to the list that
		"reflects" the "concensus" of the group.

Meeting Adjourned:

==================================================================
Un-Addressed items from the agenda:
==================================================================
Following items pending additional input:
------------------------------------------------------------------
11. Schemas in imported WSDL (no issue number) [.1]
- Seems to be agreement on the existing behavior as described by
Gudge and Amy.  Still outstanding: do we add note along the lines
of Glen's suggestion: put text in the spec to the effect that WSDL
processors SHOULD make schema namespaces embedded in the <types>
sections of imported WSDLs available to their schema processors for
xs:import where possible.

Awaiting specese sample from Glen.

------------------------------------------------------------------
12. Proposal for combining the two attribute operation styles to one
(Jacek - no issue number) [.1]
Deferred pending final disposition of attribute styles.

------------------------------------------------------------------
13. Issue 64 [.1] Operations an HTTP verbs (Mark Baker) [.2, .3, .4]
- Jacek's synthesis [.5].
- Awaiting description from Philippe showing how properties or
extensions can be used to annotate the WSDL with RESTful
properties.  Ask Mark for a definitive list of those properties
so we can consider how to associate them with property URIs or
namespaces.
- Marking WSDL operations as "safe" (DaveO/TAG) [.6, .7]
