You're absolutely right, the spec talks about HTML fragments, which,
following the specs, are not xpointers. My bad!

Mh, Ok. It must be valid for the exact media type of the source. It's
clear now.

Though, still believe that it would have been fun (and maybe useful)
allowing funky fragmentSelectors like an #xywh=* of an HTML page, or
#char-* of content coming from a PDF, or any other combination. But
since this can be done simply by defining a new selector, we will just
follow that road when needed.


Thanks again for the clarifications! :)
