Re: [xsl] Can't get expath-file functions to work in Saxon 9.5 PE

The ZIP module is not supported in 9.5.1.4.

We shipped a version in earlier releases of the 9.5 series, but we found it
was very buggy, and when we started writing tests we found the spec wasn't
really stable enough to write tests against. So we decided to pull it. We're
working with others on getting a stable specification that can be properly
implemented.

(I don't understand the problems with namespace prefix reported earlier on
this thread; if someone wants to report an issue to Saxonica then I'm happy to
investigate it, but we don't regard a message on this list as something to put
on our TODO list unless we happen to know the answer.)

pass a <zip:file> element to the expath-zip:zip:file() function, and the
simplest way I can see to do that is to create the zip:file element inside a
variable and then pass the variable to the function:
