There are issues around this, sure. We used to call it the "Content in 
Context" problem.... do you link to the source, or to derived view.
At the end of the day, that is at least partly an application question.

That said, I implemented XPointer for both match and select patterns 
in XT. With a fairly small amount of work, I might even be able to 
hook up an XLink resolver into the XSLT processor.

FWIW. I have seldom seen real cases where you couldn't project the 
range information forward through a transformation... you can always 
do intermediary fixups along the way. The *real* problem is trying to 
correlate the transformation output back to the source. XSLT certainly 
doesn't make that easy, ranges or not.
