You'd certainly need a hash mark somewhere in there if it's supposed to 
be an xpointer :-)

But more to the point, I think what Lisa meant was:

   http://example.com/page1.html/*/h:a/[@href=contactus.html]
       lisa:contentType   _:a.

   _:a   rdf:type   lisa:SiteMapLink.

(Erm. Well. Hey, I don't speak xpointer, either! ;-) )

My guess is that it would be better to treat the XML fragment as the 
link, though:

   http://example.com/page1.html/*/h:a/[@href=contactus.html]
        rdf:type   lisa:SiteMapLink.

If you need additional attributes, you can place them on the same resource:

   http://example.com/page1.html/*/h:a/[@href=contactus.html]
       rdf:type    lisa:SiteMapLink;
       dc:date     "2004-08-03"^^xsd:date.

If it's a predicate, it has to be a property. (It's AFAIK not strictly 
speaking illegal for it to be a class in addition to a property, but it 
wouldn't make sense.)

I don't understand what exactly this means -- an XML literal that 
contains information about the link? That wouldn't be illegal, but it 
certainly wouldn't seem to be good style.
