Ok, I misunderstood then. Sorry.

I agree that ideally you want tables in XHTML-IM for your use-case.

It probably is, from a protocol perspective. I don't know if it is,
from an implementation perspective, very simple. It depends what
clients are using to render XHTML-IM today, and whether they support

That seems overkill to me in this case. Perhaps we could just push for
(carefully) relaxing the restrictions in XEP-0071 that you feel
prevents you from sending tables?

The downside with this approach is that, although you could start
sending tables today and be compliant, unless tables are documented
somewhere then they won't ever be implemented in clients.

Are there any other things you find lacking in XEP-0071? If so,
perhaps some "Extended XHTML-IM" XEP would be in order?
