<type>Element</type><name>FRBRmasterExpression</name><comment>The element FRBRmasterExpression is the metadata property identifying the master expression, i.e., the expression whose ids are used as permanent ids in the wId attributes. An expression without the FRBRmasterExpression element is considered a master expression itself, i.e., the first version, or the most important version, of a document expressed in the only language, or in the most important language. Any other situation (subsequent versions, or language variants, or content variants) must have the FRBRmasterExpression element pointing to the URI of the master expression. If the FRBRmasterEpression is specified, but without a href pointing to the masterExpression, it is assumed that NO master expression exist in reality, but an UR-Expression exist, whose ids are used in this expression as wIds.</comment>
