Saxon

Calling the (unsupported/defined) function Q{http://expath.org/ns/archive}extract-map() fails with possible mutliple bindings.

This call is only documented in an editor version of the EXPath Archive spec, and not in the main specification (http://expath.org/spec/archive) which used a different namespace of map-defined forms of the functions, and as such was an experimental piece of code that stayed in the SaxonPE/EE code base.

Historically, the EXPath archive specification, which was a generalisation/development of the earlier EXPath Zip module, was never finalised and the Saxon implementation stands as that defined in the last editor's draft (i.e. http://expath.org/spec/archive/editor). In this case the *-map() calls have been implemented but, as in this case, not tested.

We'll have to consider how/whether we'll change the support.
