> looks like this would be xsl:document

You want xsl:result-document.

xsl:document creates a document node. That lets you create a temporary 
document tree against which you can do some processing in your transform, 
but it does not create a final result tree that you can then send to some 
URI.

Stealing from Mike Kay's post in this thread, here's the link for 
xsl:result-document:
