I haven't yet to have time to take a look at Abacus, but I have to followed this with great interest.

For professional as well as personal reasons there's a need for me to find/develop a special purpose xml-editor (for couple of xml dialects we are using), and mozilla
looks like it could form a basis for one.

Only it doesn't look to be too easy, having followed your and Danial Glazmans writings on the subject.

So if it were someday (soon..) possible to borrow from common code of "editor" functions/widgets etc. to build ones own xml-editor, it would fulfill few dreams of mine...

(From Alex: I know Daniel Glazman has intended to start work on a generic XML editor, but you'll have to ask him for progress reports. I very much want to be part of the project, myself.)
