OK - that removes a large part of the issues I raised. Let me see if I can 
propose some text that we could all agree on.

PS - Just to be clear these emails are all in my individual contributor role. 
That was clear when it was IETF LC comment but given this is all cross posted 
to dispatch, just wanted to be clear.

I don't think this resolves the issue. The issue is if this information
is used for a call control. Basically do proxies need to be able to look
at this to make decision about what they are going to do. We at least
need a Yes/No answer to this question from the proponents of this work
and the charter to make that clear.

Hi,

thanks for your comments on the charter proposal. Per the comments
received, we will modify bullet 5 as follows so that it is clearer:

OLD:
5. SIP elements may need to apply policy about passing and screening
 the information.

NEW:
5. SIP elements may need to apply policy about passing and filtering
 UUI.  The included application, encoding, semantics, and content
 information will allow endpoint or intermediary SIP elements to
 allow or block UUI based on the type and originator, not based on
 the actual UUI data, which may be end-to-end encrypted by the
 application.

Further discussions on this topic should happen on the mailing list of
this WG.

Cheers,

Gonzalo
