RE: [Jersey] marshalling to html templates

I can imagine that JAXB would be a perfect fit for solutions that natively
deal with documents, since HTML obviously is THE description for documents.
But I actually wonder what the sense of JAXB-to-HTML shall be like in a
generic way? I mean, how to encode a "chair", "fruit", or "car" into a HTML
document? Ain't it more the case (like Paul says) that you like to view
*descriptions* of objects (i. e. XML ---> XSL ---> HTML) instead of objects
themselves?
