A change_request_spec is a reference to one or more change requests. A change_request_spec can have any of these forms:
This refers to a single change request by its change request identifier. In a DCM initialized database, this might take either of the forms shown. In a non-DCM initialized database, only the first form is valid.
This refers to the change request with a specified number that was created in the current database. For example, 34 refers to change request 34 created in the current database.
where database_id is a DCM database identifier that describes where the change request was created, dcm_delimiter is the current DCM delimiter (# is the default), and change_request_number is the change request number. For example, B#543 refers to change request number 543 created in database B.
This refers to a collection of change requests specified as a comma separated list of change_request_id elements. For example, B#543,23 refers to change request 543 created in database B and change request 23 created in the current database.
This refers to a collection of change requests specified as a range. The range includes the change request specified by the first change_request_id to the second change_request_id, inclusive.
The starting change request and ending change request of the range must be for the same creating database. For example, 34-37 refers to change requests 34, 35, 36, and 37 created in the current database. The range A#34-B#37 is invalid because the starting change request is for database A while the ending change request of the range is for database B.
