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 values are only those specified in 1484.12.3. The component schema definition does not allow custom vocabulary values from other sources. NOTE: This component schema definition supports the validation of strictly conforming vocabulary values by checking that both sources and values are from the token set defined in the LOMv1.0 base schema.
