 Jean-Jacques,
 I agree with your analysis. In light of the charter of the newly
created WS Architecture working group it seems that it is not us
who should suggest such amendments to our charter. On the other
hand, support for attachments is very important in even today's
web services.
 As SOAP+Attachments spec has shown us, attachments can be built
on top of SOAP with virtually no direct support from SOAP. I
believe even the changes we've made in 1.2 (most importantly
changing href attribute - anyURI to ref attribute - IDREF) do not
affect the ability of 3rd parties to add attachments support to
SOAP 1.2, the changes only affect details of the support.
 If asked, I'll gladly elaborate on how I see SOAP Attachments
rewritten to work with SOAP 1.2.
 So I see a fourth option:
 d) do nothing, leave this to WS-Architecture.
 The "attachments" feature you mention in your options b and c
can be either specified by the 3rd parties or it can be part of
our final spec. I'll support addition of this feature to our spec
if a suitable draft of the feature's text is proposed.
 So to summarize, I propose we choose either d) or b), depending
on whether somebody comes up with text for b). 8-)
 Best regards,

                   Jacek Kopecky
