[Ietf-caldav] draft-desruisseaux-caldav-sched-04 PROPPATCH precondition CALDAV:valid-free-busy-set

[Gren Elliot]

Hi,

draft-desruisseaux-caldav-sched-04 Section 5.3.2  Additional 
Precondition for PROPPATCH
says the precondition is :

(CALDAV:valid-free-busy-set): One or more resources referenced in
      a CALDAV:calendar-free-busy-set property being stored on a
      scheduling Inbox collection is invalid.

Should the "invalid" read "valid"?  I can understand that some of the 
resources might be invalid due to calendar deletions or future additions 
but requiring one to be invalid seems wrong.

Regards,
Gren.
