01-C03 quota vs disk space

The spec says that servers may expose physical disk limits as quota.

a) This is incompatible with NFS from which we're borrowing the 
semantics (it treats disk limits as a separate property, and so should we)

Update -04: this still appears in the text, but is less critical now 
that authorability of the quota is gone. I'd still like to see the 
working group make an explicit decision to keep this, because it's IMHO 
clearly outside the scope of this spec (I'd prefer separate properties).


04-C07, section 3, DAV:quota-available-bytes

<http://greenbytes.de/tech/webdav/draft-ietf-webdav-quota-05.html#rfc.section.3>

   "Support for this property is REQUIRED on collections, and OPTIONAL on
    other resources.  A server SHOULD implement this property for each
    resource that has the DAV:quota-used-bytes property."

What's the motivation for the distinction? (same in section 4)


04-C11, section 7

      "The total size of a collection, DAV:quota-used-bytes, is not
       necessarily a sum of the DAV:getcontentlength properties for
       resources stored in the collection."

Actually, it won't be in most cases I'm aware of. Please either rephrase 
it (so this doesn't sound like an edge case) or drop the point.

Update -06: It's now saying

"The total size of a collection, DAV:quota-used-bytes, may not be a sum 
of the DAV:getcontentlength properties for resources stored in the 
collection."

...which isn't that different...


05-C02, Section 4

<http://greenbytes.de/tech/webdav/draft-ietf-webdav-quota-05.html#rfc.section.4>

I think this property is "computed" (as defined in RFC3253), and the 
spec should say so.




05-E01, section 1.2

<http://greenbytes.de/tech/webdav/draft-ietf-webdav-quota-05.html#rfc.section.1.2>

I'd move those parts that "import" terminology from RFC2518/3253 into a 
separate subsection ("Terminology"), and also refer to the def of 
"computed" property (I think we need that later).
