Yes, see my second post to this thread.

Secondly, if a node has children, the entire RTF is tested.

A result tree fragment, or RTF, is created by filling an xsl:variable using the content instead of the @select attribute. An RTF is a bit odd, as it's not a first class node-set. But here, we have node-sets, not RTFs.

is there a way to omit RTF's containing more than one node

I think what you're trying to avoid having flagged here is element nodes containing other element nodes. You can do this by adding the following template to the stylesheet contained in my second post:

  <xsl:template match="*[*]">
    <xsl:apply-templates select="*|@*"/>

This will match element nodes containing other element nodes, not
generate any output but simply carry on processing down the tree.

Note, however, that differences involving mixed content (element and
text nodes interspersed) will escape your notice if you adopt this
approach. Let's say there is an element that has other element children
but also text children, and there is a difference in the text children
with regard to your reference document. This difference won't get
detected; you'd need something more refined here. If you know, on the
other hand, that you don't have mixed content there is no problem.
