RE: sorting (again)

Make your first (primary) sort key be a boolean value - false if this is the
DictionaryModelDescriptor node, true if it is not. 

In XSLT 2.0 if <xsl:sort select="..."> returns a boolean, it will sort false
before true. XSLT 1.0 will convert the boolean to a string - so "false"
still comes before "true".
