Re: creating a node-set at run-time

> a specific attribute in the root node

root nodes don't have attributes so I assume you mean the top level 
element node.

Your description wasn't too clear but it sounds like you want the set of
all root nodes for which the top level elemnt has this attribue

the set of documents that have <xxx yyy="bbb"> is

<xsl:variable name="x" select="document(list/item/@ref)[xxx/@yyy='bbb']"/>
