RE: can one include/import XML data into stylesheets?

document('') gives you an XML representation of the current stylesheet
module, in its state before any processing of xsl:include. So this won't
work.

But you could put a global variable in the included stylesheet module of
the form

<xsl:variable name="x" select="document('')/*/gem:data/..." />

and then in the main module you could refer to this variable.
