The

900000000000456007 | reference set descriptor reference set| |
is a reference set used to specify the format of all reference sets included in a release. The data type and meaning of the referenced component and each additional field within each reference set is described by this reference set.
More specifically, the reference set descriptor is used to define:...
However, it is possible for a to ato specialize the descriptor template of its supertype, by creating a copy and replacing the

values values with a subtype.
For example, if ahas a descriptor, in which the

|
900000000000458008 | Attribute description | |
=

=

|
900000000000460005 | Component type | |
, then thesubtype may replace this descriptor with one in which the
