Issue WSRF24: Should the XPath evaluations in WSRF specs be made in thecontext of some namespaces defined or not

[Susan Malaika <malaika@us.ibm.com>]

I'd like to draw your attention to the approach the W3C XQuery group took in  http://www.w3.org/TR/xquery/
Note that XQuery uses XPath.

XQuery defines a host environment- What's outside the line in Figure 1 here http://www.w3.org/TR/xquery/#id-processing-model

In general, XQuery takes what the host environment gives it, adds or overrides with prolog directives, and then evaluates the XQuery expression.

Each prolog directive is different. For variables, adding a new binding will occlude a binding from the environment. (occlude : the inner scope hides the outer scope for these variables). See the tables here
http://www.w3.org/TR/xquery/#id-xq-context-components

The WSRF TC may want to contact the XQuery co-chairs before (or perhaps instead of) writing to the W3C as a whole. I've already spoken to Andrew Eisenberg (one of the XQuery co-chairs) about issue WSRF24 - so the XQuery group won't be surprised to hear from the WSRF TC.
