Section 2.2.4 Reserved metadata names and cardinality lists several superfluous cardinality constrainsts

[emetsger]

Section 2.2.4 has many superfluous cardinality constraints. A minOccurs of 0 and a maxOccurs of unlimited effectively makes a reserved name optional. Because these fields are already optional per the BagIt specification, there is no need to re-iterate optional fields in the profile; the profile is not further constraining the cardinality of the fields.

This issue proposes the following optional fields be removed from the profile to improve clarity (i.e. clarifying that the profile does not constrain the fields in any way beyond the BagIt specification):

Source-Organization: minOccurs=0, maxOccurs=unlimited
Organization-Address: minOccurs=0, maxOccurs=unlimited
Contact-Name: minOccurs=0, maxOccurs=unlimited
Contact-Phone: minOccurs=0, maxOccurs=unlimited
Contact-Email: minOccurs=0, maxOccurs=unlimited
External-Identifier: minOccurs=0, maxOccurs=unlimited
Internal-Sender-Identifier: minOccurs=0, maxOccurs=unlimited
