Re: Comments on WS-Fragment editor's draft

I'm not sure what I was smoking when I wrote up the original text, and the 
stuff currently in the spec,  because it seems very inconsistent.  Thanks 
for catching this Ram.
Let's try this version:
This Mode value indicates that the children of the Value element MUST be 
added to the resource representation in place of the fragment referenced 
by the children of the Expression element. 

This Mode value has the net effect of doing a "delete" on the referenced 
fragment, followed by an "insert" on the fragment's parent. 

If the fragment is absent, or if the Expression evaluates to an empty 
fragment, then the "delete" portion of the operation MUST have no effect. 
If the implementation is schema aware and it detects that the Expression 
is not valid per the schema then a wsf:InvalidExpression fault MUST be 
generated.

When this Mode value is used the Value element MUST be present. 

thanks
-Doug

Comments on WS-Fragment editor's draft






Based on the resolution to issues 8185 and 8193, I suggest the following 
changes [1] to WS-Fragment. Thanks.
 
[1] 
 
[Body]/wst:Put/wsf:Fragment/wsf:Expression@Mode="
http://www.w3.org/2002/ws/ra/edcopies/ws-fra/Modes/Replace" 
This Mode value indicates that the children of the Value element MUST be 
added to the resource representation in place of the fragment referenced 
by the children of the Expression element. 
This Mode value has the net effect of doing a "delete" on the referenced 
fragment, followed by an "insert" on the fragment's parent. If the 
referenced fragment is already absent then the "insert" operation is still 
performed. 
If the Value element is not present then this Mode MUST simply remove the 
referenced fragment. If the fragment is already absent, or if the 
Expression evaluates to an empty fragment, then this operation MUST have 
no effect. If the implementation is schema aware and it detects that the 
Expression is not valid per the schema then a wsf:InvalidExpression fault 
MUST be generated. 
When this Mode value is used the Value element MUST be present.
