For purposes of RETS and its GetObject transaction, a collection
of octets treated as a unit and associated with a unique resource
element.
A field or feature described by this specification but not required
for an endpoint to be considered compliant. The specification
states the action to be taken by a compliant system in the absence
of an optional field. The fact that the specification designates a
field as optional does not mean that the recipient of a transaction
that is missing optional fields is required to provide all services
that could be required if the field were present.
A compliant server or client MUST include any field designated
as required. A transaction that does not include every required
field MUST be rejected by the recipient.
A collection of data having the external appearance of belonging
to a single database and being accessible for search or update via
RETS transactions.

Key.

Request Header Fields”.
