IMHO that would be a good item to add to the security considerations in

I think XHTML-IM pretty much does what IMML does, but in a W3C-friendly
manner. If people want to support an even more reduced subset of XHTML
then I have no objections. I think clients can effectively do that via
XEP-0071. The baseline requirements are pretty minimal:


If people want something even more minimal and texty, they could simply
use Textile or some other lightweight text formatting approach:
