ok I think I understand, bear with me...

http://example.com/contactus.html lisa:contentType lisa:SiteMapLink

and

lisa:SiteMapLink  rdfs:subclass lisa:HTMLLink

I might be totally off the wall here....but I don't think you could do 
it like this, because it's the act of linking the the url you're 
interested in, not the page that the link refers to.

right so this makes sense to me. You'd have

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

(sorry, that pathetic stab at an xpointer is probably completely wrong)

I think this is how I would do it.

I'm not sure about this. I think I'd do it your way. But I could be 
wrong!
