[1] document('foo.bar') means: resolve 'foo.bar' against the URL of the
node where the XPath expression is found. Originally, this node was
itself supposed to be contained in an *XSLT* *style* *sheet*.
This does not work in XXE, not only in the context of Schematron
validation, but also in the context of macro-commands and CSS style
sheets (i.e. the xpath() pseudo-function).
(Of course,
document('foo.bar',NODE_SET_CONTAINED_IN_THE_DOC_BEING_EDITED) works fine.)
[2] Using an absolute URL or a "xxe-config:" URL should work.
[3] I hope that 'mime-types.xml' is very small because in the context of
Schematron validation, documents loaded by the document() function are
not cached.
If all these limitations are *really*, *really*, a problem, do not
hesitate to insist! ([3] is easy to fix, [1] is not.)
