Remarks

The child elements of this element are treated as components of the bibliographic entity containing the componentList. Although this is an implicit way of expressing FRBR's hasPart and isPartOf relationships, it avoids this terminology in order to prevent confusion with musical terminology. Work, expression, and item components must be the same type as the parent of componentList: work children are allowed within work, etc. Manifestations; i.e., sources, may have either source or itemcomponents as required to accommodate composite sources (those containing multiple sources) or multi-part sources (those made up of several physical items.

Constraints
Only child elements of the same name as the parent of the componentList are allowed.
When any child element has a comptype attribute, it is recommended that comptype appear on all child elements.
<sch:rule context="mei:componentList">
<sch:assert test="every $i in ./child::mei:*[not(local-name()='head')] satisfies $i/local-name() eq ./parent::mei:*/local-name()">Only child elements of the same name as the parent of the componentList are allowed.</sch:assert>
</sch:rule>
<sch:rule context="mei:componentList[mei:*[@comptype]]">
<sch:assert role="warning" test="count(mei:*[@comptype]) = count(mei:*[local-name() ne 'head'])">When any child element has a comptype attribute, it is recommended that comptype appear on all child elements.</sch:assert>
