/**
 * Represents an attribute group.
 * <p>
 * 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.
