Hi,

I have updated the latest draft text (see 
<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html> 
and 
<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-issues.html>) 
as follows:

1) Recorded and resolved those issues for which we agreed upon a 
resolution 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html#rfc.issue.2.5_language> 
and 
<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html#rfc.issue.7.1.1_add_resource_id>).

2) Recorded and resolved as "no change" the issue where the consensus 
seemed to be that we don't need a change 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html#rfc.issue.1.3_error_negotiation>).

3) Re-added issue 4_LOCK_BEHAVIOUR from the old issues list as 
<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html#rfc.issue.4_LOCK_BEHAVIOR> 
(with status "closed").

4) No changes at all where it seems that the explanations provided by 
Geoff and myself seem to have been sufficient.

This leaves us with the perma-issue of locking vs binds:

I understand that this is a property of the resource, not the binding, but since 2518 doesn't say anything about bindings, I think we could use a paragraph at some point that spells this out explicitly.  Perhaps another sub-section in section 2?

The authors of the BIND spec feel that it's a bad idea to try to clarify locking semantics in a document that's completely independant and optional. Locking semantics should be fully defined in a single place.

Another one is to factor out locking from the base protocol, and publish this as "update" to RFC2518 (at "proposed" level), and let the BIND spec refer to that. This is what I'm currently working on (and I'm planning to submit a complete rewrite in time before the IETF meeting).

It would be nice if we could make some progress on that discussion which 
has now been going on for half a year...

Anyway, unless I people feel there's a problem with that, I'll be 
submitting the latest edits as draft 06 so we have an up-to-date 
published version in due time before the IETF meeting.

Best regards, Julian
