RE: [xsl] Conditionally create an html table based upon ex

Although you stated the requirement as generating the table if its content
was non-empty, I reckoned that if either of the input node-sets was
non-empty then the table content would also be non-empty, so it's more
efficient and easier (and possible in XSLT 1.0) to test the input node-sets
rather than saving the output tree in a variable.
