I can't resist but to post it once again, sorry about that ;-):

http://greenbytes.de/tech/webdav/rfc2616.html#status.201
---snip---
10.2.2 201 Created

The request has been fulfilled and resulted in a new resource being 
created. The newly created resource can be referenced by the URI(s) 
returned in the entity of the response, with the most specific URI for 
the resource given by a Location header field.
...
---snap---

I still have the opinion that PUT+201+location+if-none-match as a way 
to create new items is in the core HTTP spec and that we don't need a 
new method nor a PUT extension for that.

IMHO the only thing which is really missing is a review on which WebDAV 
clients (few other support PUT?) have issues with a location header (or 
not).

best regards,
