TTL - Constraint
Specification of a subset of the possible content of data or metadata that can be derived from the Codelists used in a data or metadata structure.
There are two types of Constraints: Content Constraints and Attachment Constraints.
A Content Constraint specifies either the "allowable content" (used to restrict the values allowed when data or metadata are reported or exchanged), or the "actual" content (Series Keys and/or Dimension and Attribute Values present in a Data Source). In each of these cases the Constraint specifies a sub set of the full cube of data that could theoretically be present according to the specification of the Data Structure Definition or Metadata Structure Definition.
An Attachment Constraint describes subsets of the content of a Data or Metadata Set in terms of the content regions or in terms of the set of key combinations to which attributes or reference metadata (as defined by structure definitions) may be attached.
