Hi,
Mobipockect.com has some info on the html supported in Mobi books.
Check out this link:
http://www.mobipocket.com/dev/articl...TagRef_OEB.htm
and more generally this link:
http://www.mobipocket.com/dev/articl...agref_form.xml
This forms the guts of the Mobi version of their html 3.2 based markup language.
For example, just like html <sup></sup> is for superscript and <sub></sub> is for subscript, etc.
