Subject: [wsn] AI from telecon 10/11

I took an AI to suggest resolution text
to the proposed problem:
>Problem with the use of namespace prefixes in
topic and selector expressions. Client tooling may modify the the >prefixes
used
>in a web service request, so prefixes used in these expressions may
become unbound. Igor has observed a similar >problem in WS-E[6]
I propose the resolution be as follows:
For each message exchange that describes
a component that may include a QName embedded in a string, the following
normative text be included in the description of that component:
If the value of the component contains
QNames, then the namespace declarations that specify the mapping of the
QName's prefix to an actual namespace URI can be found amongst any namespace
declaration in scope for the component. Note: Some XML processors
MAY modify the namespace declarations. Designers should be aware that such
transforms exist and may render the expression incoherent, as it is likely
the change in namespace declaration will not update a QName embedded within
a string.
