Re: Calling subdocuments with processing directives

Michael's expression was equivalent to the one I suggested, in both
cases $docs could be a variable of that name or any xpath expression
that returned a sequence of document nodes, so for exanple

<xsl:variable name="docs" select="doc('a.xml'),doc('b'xml')"/>

or

<xsl:variable name="docs" select="for $d in //link/@href return doc(concat($d,'.xml')"/>


or whatever else you need.

I'd guess it's really just an efficiency issue, the system only needs to
index documents on which key() is called. If calling key() could access
any document known to the system, then the system would have to index
all documents if the stylesheet used key at all.
