Hi Jan,

I believe that addressing the techniques by functionality is a good 
decision, although you have seen is tricky. I have some comments.

1) "Direct and direct" as pointed by Charles, are not common terms. I 
would name the category "Document markup creation". I would split the 
categories in WYSIWYG editors and direct editors. I also would include 
here: HTML, xHTML, XML, XSL, XSLT and CSS editors, and remove XML from 
5. Also, I think that the inclusion here of multimedia, just because of 
editing directly the code is kind of artificial. I would leave that in 
the second category.
2) Here I would include any multimedia, also SMIL, SVG, etc.
3) As examples in 3, you might include Portal tools, for example.
4) In 4 I would include Javascript, PHP, ASP, VBscript (any script in 
general), Java (applets), etc. and move X()ML to 1). Like you point out, 
here shall go any proprietary format: Flash, Director, etc.

Regards,
carlos
