3.4 Additional definitions

3.4.1
component relation constraint
a constraint on the values of a set type or sequence type which is textually associated with one of the component types (the referencing component) of the set type or sequence type, and which specifies the relationship between the value of that component and the values of one or more other components (the referenced components)

3.4.2
constrained type
the innermost "Type" which contains the referencing component and all of the referenced components of some component relation constraint

3.4.3
constraining set
the information object set referenced in some component relation constraint

3.4.4
constraining table
the associated table (see GB/T 16262.2-2006, Clause 13) corresponding to a constraining set

3.4.5
referenced component
a component of a set type or sequence type identified in a component relation constraint

3.4.6
referencing component
a component of a set type or sequence type which has an associated component relation constraint
