Synonym(s) CompositeElement

Comments	Scope: A Composite can be used to describe any class of formal relationships, althought typically a Composite represents a complex formal data structure such as an XML schema complex type, an OO ObjectClass or a relational database table. Composites may contain other Composites to any level of granularity. Composites may be used to represent both classes and instances of schemas.
	Example: Examples: an XML Message, a set of ReferenceDescriptiveMetadata, a group of elements within a Message such as 'TitlesComposite'. A Composite does not represent anything in its own right but is only a collection or 'bag' of entities which normally have some kind of relationship. Composites may contain other Composites to any level of granularity.
