I'm trying to summarize the two things you would prefer to see changed. Tell
me am I getting this right?

1) The document REQUIRES the attributes that report the used and remaining
bytes of quota space to exist on collections but makes them optional on
other resources. Some WG members feel it would be better to required on all
resources but are OK with how it is written now.
 
2) In 2518, if a Dav server that had a disk full situations, the server
would return a 507. Now with quota there are two reasons a 507 could happen,
a disk full (as before) or a quota exceeded. The quota exceeded is a very
similar but slightly different error. To enable a client to display an error
message to a human user to differentiate these two things, a server that had
a disk full error would return a 507 with a DeltaV style error body that
indicated the disk was full. Is your issue that a) this should not be
defined in the quota document b) you don't think we should do this at all
and the DeltaV error for a disk full should be the same as the response for
quota exceeded? In trying to summarize the issues I realized I did not
understand what you were concerned with and more specifically exactly what
you would propose we change to fix the concern.


Thanks, Cullen
