I certainly hope that some people would express their views, I'm not
that experienced:-)

First I was thinking about using libxml's or expat's SAX interface (and
using c++ and fltk btw.)

But I want to create a www-like XML format+DTD for music (borrowing
from MusicXML and MusiXML, but with some nice ideas) that should
eventually be usable to display in a browser like SVG or MathML, with
a scriptable DOM.

So just to exercise for that, I would like to try to use the libxml2
to hold the document while editing, so that in fact all interaction
occurs through some sort of DOM. (Also I plan to support style tags
and stylesheets like XHTML, for scaling, coloring etc.)

Ah, the *_private! I thought it was used by libxml2 internally.

Thanks for help and sharing your views,
Wilbert
