Interesting question, but I'm going to be nitpicky. 
You describe two things,
 i) some random XML instance document
 ii) a personal interest in the purchasing of an object with certain 
     characteristics specified at various levels of detail.

Are you asking how we can find out whether the XML document, when read as 
making assertions about the world , makes any assertions about an object
that fits that description?
or more specifically, whether it makes assertions which
allow us to realise the object fits yr desire description, _and_ that 
provide some clues for where and how we might set about acquiring said object?

I ask since your question is couched in terms of the XML instance 
meeting or not meeting the purchasing desire. Since being an XML infoset 
is quite different from being the purchase of a camera, it isn't exactly 
clear what you mean by 'meets this desire'. I guess you mean something
like 'helps me meet this desire somehow'...

thanks for the work on the camera ontology btw, it is good to have 
practical examples to help make these discussions more concrete!

cheers,

dan
