Summary: This draft is basically ready for publication as a Standards Track
RFC, but has some nits that should be fixed before publication. [Ready with

The draft specifies a framework for use in provisioning session
establishment data into Session Data Registries and SIP Service Provider
data stores, just like it says in the abstract.  It does not provide a
concrete protocol for these operations.  Most of my comments have to do with
niggling readability issues, not the substance of the document.  It seems
quite reasonable for its stated purpose.

Major issues: None

Minor issues: 

I'm not sure I wholly comfortable with how the framework describes the
protocol be created from it as a "transport protocol".  That term is
somewhat loaded in network and in the Internet is generally thought of as
meaning a protocol such as TCP or UDP.  Furthermore, the operations that are
carried out by the protocol specified in the framework are all that
applications layer and rely upon other application layer protocols to
perform security vital functions such as authentication and authorization.
Perhaps a less loaded term could be used?

Section 7.2: Is the "Delete" operation meant to be atomic?  Should that be
specified in that section?

Section 9.7: this section discusses how the "transport protocol" provides
connection protection services and then says that therefore a
man-in-the-middle attack is possible.  If that's the case, then the
"transport protocol" is not (adequately) providing connection protection.
And without connection protection, a man-in-the-middle attack would of
course be possible, so saying that because there is connection protection, a
man-in-the-middle attack is therefore possible seems misleading.



There are a few occurrences of "e.g.  XYZ" (that is, "e.g." followed by two
spaces and something (XYZ)).  Replace the first space with a comma, which
should be easy with a general search-and-replace operation.

Change the few contrary occurrences of "source based" to "source-based".

Insert "the" consistently before <xyz> when talking about an element.

with "ability".

Change "applies" to "apply".

Page 10, section 3.2, 1st paragraph, 3rd sentence: insert "a" before "time".

Page 11, section 4.1: do you really mean "point-to-point" or "end-to-end"?
In any case, insert "a" or "an" before the correct choice, as appropriate.

"large datasets".  Insert "of" between "millions" and "records".

Consideration" to "IANA Considerations".

operation".  Consider changing "add" to "Add".

Page 22, last paragraph, 2nd sentence: is the span meant to be inclusive or
exclusive of the starting/ending TNs?  I'm guessing inclusive, but it wasn't
utterly clear from the text and might be worth spelling out.

Page 23, last paragraph, 2nd sentence: insert "the" before "open plan".

Page 36-37, section 7.2, each bullet item: I think the "as part of
fulfilling the deletion request" can be safely left out in all cases.  It
should be obvious from the lead-in material that these rules only apply in
that case.
