<xs:simpleType name="NOTATION" id="NOTATION">
  <xs:restriction base="xs:anySimpleType">
    <xs:whiteSpace value="collapse" fixed="true"/>
  </xs:restriction>
</xs:simpleType>

Description

The value and lexical spaces of xs:NOTATION are references to notations declared though the xs:notation element. The use of this element and datatype is, therefore, a namespace-aware emulation of the NOTATION feature of XML 1.0.

Restrictions

Notations are very seldom used in real-world applications.

One cannot use xs:notation directly, but must derive it as shown in the Example.
