-<xsd:annotation>
 <xsd:documentation>The unique identifier of an object. This should not be used for child nodes within an object. For an independent object, the value may be globally unique. For a dependent object, the value must be unique (for the same object type) within the context of the parent object. There should be no assumption as to the semantic content of this attribute. The purpose of this type is to facilitate modifying the optionality in derived schemas.</xsd:documentation>
