The pre-Zope 2.6 tracebacks have been optimized for DTML but were
bad for PageTemplates. As PageTemplates became mainstream, for Zope 2.6,
Shane overhauled the traceback generation and optimized
them for PageTemplates. Unfortunately, the overhaul lost
the DTML optimizations.

I have a small patch such that the modern traceback at least tells
the name of a DTML object. Almost surely, it would not be difficult
to extend the traceback generation to provide the former
additional information -- but we rarely work with DTML nowadays.
Therefore, the need was not pressing enough for me to investigate...
