This component schema definition provides simple type declarations for LOM data elements that are defined as Vocabulary data types. This component schema definition enforces that vocabulary sources and values are character strings, which simplifies the schema validation process for those applications that perform vocabulary source/value validation using post-schema-validation. This component schema definition relaxes the validation constraints by allowing both sources and values to be arbitrary character strings. NOTE: The absence of the enforcement of vocabulary values does not relieve a particular LOM XML instance from satisfying vocabulary requirements defined in the LOMv1.0 base schema. Applications that require the use of vocab/loose.xsd component XSD should enforce those vocabulary requirements by other means.
