My example was a bit simplistic. This transformation is
no more difficult in fully blown SGML that it is in XML.

The fun starts for the D&lang;H when including the markup in the
SED command is not an option due to the hierarchical sensitivity of
the task. e.g. just telephone numbers occuring within 
the appendix elements and skipping those where the client attribute
has the value = "Jones". That sort of thing.

Maybe nothing short of a fully blown XML parser will do for these
