Speaking in no official capacity for WS-Desc, I believe we will
indeed support the description side of MTOM. Philippe, isn't this
one of the WS-Desc action items you've got on your plate?

There are two issues here:
1) support for media types in XML, and
2) support for MTOM at the binding level

My understanding was that Philippe's AI was for (1) and not (2)

I think cross WG support would be great, but we can achieve that
informally too if necessary as there's sufficient overlap IMO.

Jonathan, Philippe,

You didn't respond to my previous note below. I've been asked by the
XMLP WG to try once more to obtain an answer. If you don't respond
within a week we'll assume your silence means that you do not intend to
tackle the description side of MTOM in the WSD WG.

Jonathan, Philippe,

I have an action from the XMLP WG to follow up on the recent
discussions regarding WSD support for attachments. Are you able to
confirm that the WSD WG is going to tackle the description side of the
MTOM (nee PASWA) work currently underway in the XMLP WG ?

Thanks for any information.

I certainly don't want to do the work on the XMLP WG :)
And similarly I don't want to do the work of the ws-desc WG ;-).

The reality is: the technical decisions of the WSD WG for embedding
media types in XML Schema will impact on the work done in the XMLP
Since the reverse is true, both WGs need to be aware of their work
make sure we coordinate on it and reach the same conclusions.

I agree and +1 Mark's comment[1] that I think we need a cross WG task
force of some kind.
