I really don't like using line numbers for this other than in an editing
environment because if you are programmatically building up a DOM tree, line
numbers do not apply.  However some sort of XPOINTER mechanism for flagging
errors would be great IMHO.  In other words location is defined by an XPointer
rather than a line number relative to the owner document.  I think this sort of
error flagging would be much more useful.
