I was trying the graphical view of TEI Relax NG schemas in oXygen 6
and I was impressed. Really nice tool.
One thing that will make all this even better over time is if we can
get the documentation which appears in these schema displays
translated into other languages. The mechanism for implementing this
is all in place, and we can use the Roma interface to specify it,
so we all need now is an awful lot of words translated :-}
(the TEI Board has plans to look for funding to do this, by the way).
