Ralph,

Unfortunately I don't have any experience with StructuredTextEditor.
I've always wanted to use it to provide a source view in the generated
editor, but since WTP depends on EMF we couldn't add a reverse
dependency. But I think WTP's features were restructured in the last
release to separate out the XML editor support, so I think it should now
be possible. I've added the WTP newsgroup to the reply since someone
reading that group may have more experience with this type of problem.
Feel free to open a bugzilla enhancement request for EMF to look into
generating a source view. I suppose we could do something very crude
like is done for the sample XSD editor, i.e., when the source changes,
reparse the whole model and when the model changes, regenerate the whole
source. But doing something incremental at the level of individual
changes to nodes in the DOM and change to EObjects in containment tree
would be very interesting. Certainly all the notification mechanisms
are in place to support that level of granularity. (I'm not promising
we'll do this, but it's something I've always wanted to do.)
