i looked at rfc 3966 (the updated version of rfc 2806) and noticed that
'telephone-subscriber' allows '*par' after global and local numbers, 
which translates to parameters, extensions, and isdn subaddresses, and 
we don't want to have these par things. but even if we decide to not use 
'telephone-subscriber' but the two productions 'global-number-digits' 
and 'local-number-digits', the latter also allows the '*' and '#' signs 
you did not want to have. any suggestions how to resolve that? it was my 
understanding (and something that claudio allocchio pointed me to when i 
started writing the sms uri drafts) that rfc 3601 was intended to be 
used whenever phone numbers need to be used in internet standards.

i have now combined all three drafts into one draft, which merges the 
security sections and contains the registration forms as sections.

new: "This attempt to collect information may be a privacy issue, and 
user agents MAY make users aware of that risk before composing or 
sending SMS messages."

i don't get this one. is it not allowed to have a MUST if the control is 
at the user agent? i guess this is just what i want to do here, i want 
to say what a user agent MUST do under certain circumstances.

do you suggest do re-write or re-phrase the whole section or just parts 
of it? right now it is a set of issues which are often unrelated, so i 
assume your comment is about all or most issues and not about specific 
one you find hard to understand?

ok, as i said above, the new version will be only one draft, including 
the two registrations as sections. i want to improve this new draft a 
bit before i submit it again, mainly in the security section, which 
seems to be the biggest problem.

cheers and thanks for the comments,
