We have several tools to deal with [XML]: [TclXML], [tDOM]... which serve the same purpose with different interfaces. It might be a good idea to unify those under a single Tcl interface, so one can plug in different implementations (including the gnome XML libraries...)
----
Please explain why this is necessary?  I think in general development, people pick the tool they like the best
and stick with it.  So what advantage would I have if I used a single interface?  I always wondered about this
same problem with SQL interfaces.  The example I can think of is the '''ns_db''' command in AOLserver.  Yes its 
great. However it only provides a basic interface to SQL databases.  Look at the Oracle driver.  It had to create
its own command to implement things such as binding.  Is it possible that a single XML interface could susceptible
to the same problems?

Anyway, I think that TclXML has such an interface.
