10. Issues
Issue 3484 
	- dealt with in last meeting
Issue 3568 
	- no proposals
	- Remove this issue from the list until proposal raised
	Monica: A choreography initiator interaction MAY be defined within a root choreography or within an enclosed choreography. In either case the collaboration is established when the first choreography initiator interaction is performed.
Issue 3843 
	NEW ACTION: Tidy up section 5.7 initial paragraphs that talk about initiator interaction

Notification issue
	Martin: understands requirement for notification, to enable server to send message back to client
	Martin: does not understand how with current WS technologies, how can guarantee usage without binding problem
	Steve: How do we see C-CR-1002 in relation to this issue
	Steve: Namely "choreography MUST be independent of implementation technology"
	Steve: And how do we see C-CR-2301
	Steve: "A choreography language MAY provide a mean by which a choreography description can be bound to technologies other than WSDL 2.0."
	Steve: And what about:
	Steve: <roleType name="NCName">
	Steve: <behavior name="NCName" interface="QName"? />+
	Steve: </roleType>
	Steve: where QName is optional.
	Martin: we as a group should be focused on web service capabilities, and in this context there are problems with bindings for representing notifications
	Martin: I am aware I being a web service purist here
	Monica: Agrees with Martin - CDL in current version has significant leaning to WSDL
	Monica: questions where now is the right time
	Martin: +1 to monica
	Martin: Steve that optionality is because some roles are client ones and dont provide WSDL, not that WSDL itself is optional
	Gary is prepared to withdraw proposal.
	Martin is prepared to accept proposal if a binding can be shown to work with WSDL 2.0 and WSDL1.1 (have I got this right?)
	NEW ACTION: Close notification issue, pending further demonstration of the ability of bindings to support it
	NEW ACTION: Chairs to liase notification binding issue with CG meeting
	NEW ACTION: Process for applying edits to spec

11. AOB
	None
