All Implemented Interfaces:
    SchemaAnnotated, SchemaComponent

All Known Implementing Classes:
    SchemaAttributeGroupImpl

An attribute group is a syntactic construct, not a part of the logical model. For example, types declared within an attribute group become local to the type that uses the group - they're not local to the attribute group itself. Therefore in the logical model of a schema type system, an attribute group doesn't represent anything. Its contents are merged into the logical model at parse time.
