Yes, Dan's simple pointers point to XML elements rather than the
description component, per the XPointer spec if we keep compatible with
it for our media type (and we should!).  If that is sufficient for his
use he's free to do so, and even possibly layer on higher-level
inferences of equivalence between the element and the component within a
particular domain.  But testing XPointer is not something I feel the
WSDL WG should engage in.

 

However. my job here is simply to bring a clear issue, hopefully with a
proposal, before the WG for resolution.

Jonathan, 

We don't have any test cases for the frag ids yet. However, if we do add
them, I don't think this implies we test Dan's proposal since it is very
problematic and not part of the spec. 

Isn't it the case that if users want to use simple fragment ids, they
can add an attribute of type ID to the element they want to reference?
That is allowed by the WSDL 2.0 schema. Wouldn't that we the correct
normative interpretation? The XPointer Framework calls these shorthand
pointers [1].

Since component designators aren't used internally by WSDL I would guess
we would not conduct tests of them, indeed I'm not sure what that would
mean.  But the WG hasn't discussed this yet.  I'll try to bring it up
when we move to CR.
