[sip-clf] draft-ietf-sipclf-format-01, optional fields

[Anders Nygren <[e-mail]>]

Hi
I hope this is the last from me for this version.

In the descriptions of the optional fields I think that there some things
that should be clarified.

- Can the optional fields be in any order, or do they have to be sorted
by increasing tag values?

- If an optional field represents a SIP header, e.g. Contact, can appear
several times in a SIP message how are they logged, as several optional
fields with the same tag, or does the all the Contact headers have to be
concatenated in the value of one optional field. (I think that draft-00
explicitly stated that the contact optional field could be repeated, but that
seems to have disappeared in draft-01.)

-If an optional field can be present several times, do they have to be adjacent
or can they be mixed with other optional fields?

- figure 1 shows that the optional fields are before the vendor extensions.
If we have the same format for standard optional fields and vendor extensions
is it still a requirement that they be separate, or can they be mixed.
