Using multiple elements with different grouping keys shouldn't be a problem,
because you can declare multiple <xsl:key> elements with the same name and
you effectively get the union of all of them.

Grouping across documents is more tricky, because the scope of a key is
restricted to one document. You probably have to build the composite
document as a temporary tree and then do grouping on that.
