Re: [vwrap] The <embed> tag... is the group still interested in LLSD or DSD?

We will certainly need to have a protocol negotiation handshake if we have
any pretentions of being "extensible", and this negotiation phase needs to
be present in all serializations, including binary ones.  Carlo's advice
about this is good.

Version 1.0 for VWRAP needs to be as good as we can make it though, not the
current LLSD spec which is clearly very limited.  Knowingly keeping it
inferior and immediately creating problems for everybody is a very poor way
to proceed.

I recommend that if you want LLSD/DSD unchanged from its current spec then
you should publish it as an RFC, and avoid all these discussions.  Here in
VWRAP we have a far more onerous duty, which is to publish a *good* types
spec.

Morgaine.
