It would be more accurate to say that we have not identified a WYSWYG tool
which does not mess up the source. There may be one, it would just take a
fair amount of testing to find it.

Yes, and graphically-enhanced tag support using XML IDEs. Command-line tag
completion is available via Emacs-SGML, but there are a lot more tools
which do it for XML (including Emacs).
