As the

Gloss
SpacePreSpacetruefalse
trelease file
formats contain a number of
Gloss
SpacePreSpacetruefalse
tconcept
enumerations, it is necessary to define sets of
Gloss
SpacePreSpacetruefalse
tconcepts
that represent the allowed values. As well as the enumerated values, other metadata supporting the extensibility mechanism and the
Gloss
SpacePreSpacetruefalse
tconcept model
is required.

The

is a

of the

PreSpacefalse
troot concept
(

), and contains the metadata, supporting the release.

The

are described in the following table and the top three levels of the hierarchy are shown in the figure below this.
