Remarks

The child elements of this element are treated as parts of the bibliographic entity containing the componentGrp. Although this is an implicit way of expressing FRBR's hasPart / isPartOf-relationships, it avoids this terminology in order to prevent confusion with musical terminology. All children of a component must be the same type as its parent: only work children are allowed within work, item in item, etc.

Constraint

Only child elements of the same name as the parent of the componentGrp are allowed.
