	Greg Ritzinger	257	A Choreography Language is not an "executable business process description language" [16' 17' 18' 19' 20] or an implementation language [23]. The role of specifying the execution logic of an application will be covered by these specifications; by enabling the definition of the control flows (such as conditional' sequential' parallel and exceptional execution) and the rules for consistently managing their non-observable business data.	A Choreography Language is not an "executable business process description language" [16, 17, 18, 19, 20] or an implementation language [23]. The role of specifying the execution logic of an application will be covered by these specifications.

Perhaps each of the items enumerated in the first two bullets should have its own bullet in order to "stand out".

	Greg Ritzinger	295	Choreography Life-line expresses the progression of a collaboration.

	Greg Ritzinger	303	Choreography Finalizer Block - describes how to specify what additional interactions should occur to reverse the effect of an earlier successfully completed choreography		Coming from a programming perspective, a finalize block is a part of a try block that is executed in either the normal or abnormal execution cases. I think we should stick to convention and use the term "compensate" or something close to it.
	Greg Ritzinger	322	A WS-CDL document is simply a set of definitions. The WS-CDL definitions are named constructs that can be referenced.

There is a package element at the root and the individual Choreography definitions are inside.	Insert a schema or document example here.
	Greg Ritzinger	327	A WS-CDL package contains a set of one or more Choreographies and a set of one or more collaboration type definitions, allowing the various types whose use may be wider than a single Choreography to be defined once.		Types of what? At this point I have no idea what a "collaboration type definition" is or how it affects this paragraph. Either define it or link to its definition.
	Greg Ritzinger	381	WS-CDL documents MUST be assigned a name attribute of type NCNAME that serves as a lightweight form of documentation. The targetNamespace attribute of type URI MUST be specified. The URI MUST NOT be a relative URI. A reference to a definition is made using a QName. Each definition type has its own name scope. Names within a name scope MUST be unique within a WS-CDL document. The resolution of QNames in WS-CDL is similar to the resolution of QNames described by the XML Schemas specification [11].	• WS-CDL documents MUST be assigned a name attribute of type NCNAME that serves as a lightweight form of documentation.  • The targetNamespace attribute of type URI MUST be specified and the URI MUST be absolute.  A reference to a definition is made using a QName. • Each definition type has its own name scope.  • Names within a name scope MUST be unique within a WS-CDL document.  • The resolution of QNames in WS-CDL is similar to the resolution of QNames described by the XML Schemas specification [11].
	Greg Ritzinger	392	If desired to extend the WS-CDL language' this specification allows inside a WS-CDL document the use of extensibility elements and/or attributes defined in other XML namespaces. Extensibility elements and/or attributes MUST use an XML namespace different from that of WS-CDL. All extension namespaces used in a WS-CDL document MUST be declared.Extensions MUST NOT change the semantics of any element or attribute from the WS-CDL namespace.	To support extending the WS-CDL language, this specification allows the use of extensibility elements and/or attributes defined in other XML namespaces inside a WS-CDL document. Extensibility elements and/or attributes MUST use an XML namespace different from that of WS-CDL. All extension namespaces used in a WS-CDL document MUST be declared. Extensions MUST NOT change the semantics of any element or attribute from the WS-CDL namespace.
	SRT	217-219			does this mean no WSDL is required? Does it mean same WSDL is  required? Does it mean different WSDLs are possible?	We need to figure out what this may mean. The text is abstract enough to incorporate any direction that we choose to take.  The current situation would suggest that WSDL2.0 is required. (see line 250)
	SRT	269-270			Does this mean WSDL2.0 or earlier or both?	See section 1.4
	SRT	295, 299, 503,…			Do we need the term "business processes"? Can we just have "processes" since WS-CDL may be used in areas in which the term business process has less relevance.	Yes okay.
	SRT	321-322			Semantics allow the creation of descriptions that can record the semantic definitions of almost every single component in the model If it is "almost" then what is excluded?	We need to verify what almost means. We need to check why it is not included in some constructs. Need to file an issue and follow it through
	SRT	441, 459			Dumb question from me. What is the relationship between 'role name="ncname"' and 'role type="qname"'.  Maybe I don't understand what ncname is. I presume qname is qualified name relative to some schema.	ncname is not a qname - so not qualified. Begs the question why one over the other - that needs clarification. namespace names are qnames and thing in the CDL that are ncnames define names in the CDL namespace which is why target name space is in a CDL
	SRT	Section 2.3.3 (Relationships):			Would I be correct in thinking about a relationship as a static connection between processes?	If a process is an abstraction of some named behavior then this correct at least for one case. Kind of makes sense.
	SRT	321-322			Back to Semantics above: What would semantics be and how would the look?	Semantics are descriptive text which may be structured in RDF to enable other tools to make some assertions about a CDL.
	SRT	449, 547-551			Does this mean that a channel is a web service and so they are coupled?	This is an abstraction layer. Today it is bound to WSDL2.0. But should this need to be changed it can be without any adverse impact.
	SRT	534-535			Is there any reason not to have numbers other than 1 and unlimited?	This is really question for our invited experts.
	SRT	573			Is the <token type="tns:purchaseOrderID"/> the effective correlation id in  this example? Is this how correlation will be performed relative to channels?	Yes
	SRT	579-580			that can influence the observable behavior In what way can a WS-CDL document influence behavior since it is a description? Does this only apply to generation in which case I can see such a relationship?	Yes the latter question is right.
	SRT	602-607			Do these variables describe the relationship between messages? i.e. A is composed of specific parts of B Is this correlation?	No it is not intended to be correlation. It's sort of alpha renaming on the one hand. It could be used to guide skeleton generations for variabled on invoke and receive in BPEL.
	SRT	624			a Channel Variable could contain information such as URL to which a message should be sent Is this a "could"?	Depends on channel type and so is a could.
	SRT	674			What is a silent-action used for? Alas no example to illustrate.	The silent-action represents something that is not observable.  Perhaps our invited experts might help us with a use case.
	SRT	739-745			Given the definition previously why is "part" valid? Is this an XQuery thing?	This is a mistake. "Part" should be removed.
	SRT	748			Is "prescribes" the right word here?	Describes is better
	SRT	872-878			How do I guard with more than one variable? Is there any notion of existential qualifier associated with this so that I can have a guard that simply says: If there exists an x, y and a z then ....	You can use as many variables as you wish. Extension functions on XPath in the WS-CDL document include getVariable.
	SRT	Section 2.4.8.1 Exception Block.			How is the guard in an Exception Block work unit related to the non-exceptional work units in the enclosing choreography? Are they always the same? Are they always non-overlapping? Are they unrelated? Is it user defined? What is the consequence of un-restriction?	It probably doesn't make sense for the same guard to be used. Raises some model checking issues because there may be a need to validate guards against one another.
	SRT	1094-1099			What if there are no matches for an guarded work unit in an exception block?	See above? The exception block might well be caught higher up. No explicit final catch all is defined in CDL.
	SRT	1177			Activity-Notation "+". This allows 1 or more not two or more.	Yes it should be two or more. You can express this in the schema however.
	SRT	1211-1212			Is it possible to model a one way receive?	An interaction is a pair.
	SRT	1271-1283			Does this mean that some higher order messaging protocols allow states in the CDL to be inferred rather than captured explicitly? (i.e.  if I know that when I send a message from A to B that B gets the message then I can infer something about the state of B relative to the receiving of that message.)	No you cannot infer. It does not guarantee that B read the message as opposed to just received the message. What is needed is guarantee of understanding of the message that was about.
	SRT	1312-1313			If align and initiateChoreography are not present what is the default behavior (true or false)?	Align is defaulted to false.
	SRT	1355-1359			Default behavior again?	See above.
	SRT	1583-1596			Not sure why you use the terms "this" and "free" and what they might mean? Is it to indicate that the fromRole is the "this" and the toRole is "free based on being the initiator (i.e. Directionality?)	this is a variable is the aliased name of the free variable.

	SRT	227-228			Can you provide an "e.g." to elaborate what Composability might mean?
