So, if I want to get structured xml file I need to either redefine all
usual command to be tagged (start/stop) and, that is more logical define
my own tag commands. IMHO the use of 'important' as in example above is
logical, the actual presentation of 'importtant' words could be define
separately and in different ways (I like idea of xml+styles).

E-er, yes. I don't see characters (my terminal use UTF8 and good font)
even now. But I saw them in web intterface to ML (contextgarden because
another shows something different). Also I saw tthem in Emacs. AFAIU,
this is in private region of Unicode, these are _italic_ E, m and c. I
thought that there should be letter from ASCII (codes < 127).

Well, this were simple tests. I'll make more complex one in next weeks.
Texts, with font switching, maths, images, tables. I want to have tool
using which I could convert from one source to several formats (pdf,
xhtml, rtf/odt).
