I suspect octet offsets are more useful so one can do pointer math.
Clearly one can transform between offsets and line/column positions with a
table indexed by line number, so this could be on either the Client side or
the Implementation side.  If we're going to go to the trouble of adding
this to SAX (my vote: it's nice but I can live without), I'd do the thing
that's nicest for the Client.

Thanks,
David
