Hi,

I was looking at the current edits and couldn't help noticing that it 
again contains stuff that wasn't announced at all. As far as I can tell, 
drafts submitted to the IETF should optimally represent the working 
group's consensus, and putting in stuff silently into the working edits 
doesn't seem to be the best way to achieve this.

In particular:

1) "Hosting malicious scripts executed on client machines" 
(http://greenbytes.de/tech/webdav/draft-ietf-webdav-rfc2518bis-latest.html#rfc.section.19.8>) 
looks interesting; but I don't see an issue raised for this topic. In 
particular, the recommendation to strip script from HTML pages looks a 
fishy (upon GET? PUT? for all users?). This certainly needs more 
discussion if this should be added to the spec.

2) Summary of changes from RFC2518 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-rfc2518bis-latest.html#rfc.section.B.3.1>):

> B.3.1  Summary of changes from RFC2518

>    behavior.  A more complete list of changes has been published in a
>    separate document.

Really? I think readers of the spec really would prefer to have a 
complete (not only a "more complete") list right here.

- The response bodies for errors are optional, right?
- What did change regarding the other response headers?

(to be discussed)

"DAV:no-lock" is no new requirement.

>    Support for UTF-16 now required (ref (Section 18)).

I don't think the requirement changed. The spec merely wasn't properly 
repeating what XML defines, and this was fixed.

That affects servers as well, right? Maybe splitting the list in two 
parts isn't worthwhile.

Missing changes:

- PROPFIND dead-props 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-rfc2518bis-latest.html#rfc.section.13.28>)

- implicit lock refresh removed (see 
<http://greenbytes.de/tech/webdav/draft-reschke-webdav-locking-latest.html#rfc.section.B.1.1>)

...and potentially more.

Best regards, Julian
