This can be achieved with XHTML-IM already.

This can also be achieved with XHTML-IM. The bridge developer would know
what markup is being used on the other side, and could translate it
directly for each client, thus sparing clients from each having
flawed/vulnerable implementations.

Not every client implements $MARKUP.


It is beginning to feel like I'm banging repeatedly on this particular
drum, but years of experience on the network with clients that use fairly
arbitrary lightweight markups based on organically grown use of puncuation
for emphasis (ie, the same stuff that grew into Markdown et al) suggests
that:

a) This stuff is already out there, so adding an indicator that
interpretation in this way is desirable is useful, and
b) The lack of such interpretation, or inability to understand it were it
there, has presented no barrier to interop.

That said, I note that I am referring to IM messaging - Flow is talking
about gatewaying to conferencing systems, which lean toward long-form text,
and that typically involves a somewhat more involved markup.

This is being discussed on another thread, though, how does that compare
to vulnerable markdown implementations?


I read this as "My preferred technology is a proven security nightmare.
Yours, despite all evidence to the contrary, might be. Therefore we should
continue to use the security nightmare I happen to prefer."

I reiterate, several clients in use already use lightweight, human-readable
markup. I see zero security issues as a result.


Thanks,
