RE: Building XML from XPATHS in XSLT 2.0

Some thoughts to help you specify the problem more precisely:

You presumably mean "build an XML document for which none of these XPath
expressions returns an empty sequence."

You say "any valid XPath". Are you restricting this to path expressions?
Absolute path expressions? Are they always evaluated with the root as the
context node?

In general of course there may be no solution. For example if you have two
paths /a and /b there is no document that gives a non-empty answer for both.
