another interesting feature I use very often is to extend the XHTML namespace and just use custom attributes like isDisabled, isEditable and such stuff.
At any rate, your browser will ignore these attributes and you will have access to them via getAttribute, if you want a validating xhtml file, you should also add a custom dtd file. Check this out: http://www.w3.org/TR/xhtml-modularization/dtd_developing.html
Hope this helps!

Hi Klaus,
thanks for your answer and your hint to w3! So it seems to be a common
technique. I was wondering if I am the only one doing this, but it's
good to know that I have accomplices out there ;-)
Cheers, Arash
