Change text regarding inclusion of edit link in collection member representations from MUST to MAY.
There is no reason to require this inclusion and it makes little sense in the context of a read-only collections. Inserted without WG approval.
Change the MUST in the third sentence of Section 8.2 to a MAY:
8.2 Entry Collections Entry Collections are collections that restrict their membership to Atom Entries. They are identified by having an app:member-type of "entry". Each member representation MAY contain an atom:link element with a relation of rel="edit" that contains the IRI of the member resource. Member representations MAY contain an app:control element (Section 10.2).
