Thank you all for a very useful discussion.

Our technical author uses structured FrameMaker for the heavy lifting but for
quick and casual editing I have been using emacs and sublime text. I've had
the nxml emacs module enabled which is XML-aware but I had never heard of the
relax-NG option, so thank you Dave for that.

 It set me to hunting what might exist by way of similar packages for Sublime
Text, and I found one called Exalt. It doesn't force only valid input but it
does have a single keystroke validation function which highlights any
validation errors. I didnbt have to do anything smart by way of setup; if
the DTD or XSD referenced in the document header exists in the local
filesystem it just uses it.

cheers

I believe so, but as they can be rebound it's not very important.
I prefer psgml's way of presenting the attribute panel, but that's probably a
personal feeling.

The biggest stumbling block is that on current installations, psgml simply
won't execute: "xml-mode" has been grabbed by nxml, and my elisp skillz are
not adequate to resolve this.
