no the intention is an extension function taking two arguments
typeOf(node,typeQname)
note that this assumes there is some 'active' schema present. one could more
generally do:
typeOf(node, typename, schema)
and note that the 'schema' need not _only_ be an XML Schema, for example one
might have a simple XSLT file:
<xsl:variable name="person.type">
father|mother
</xsl:variable>
etc.

i missed what you were doing. its correct (the first "." is implicit?)

that doesn't work because a node may have many types.
