Can you please supply an example of using checkConstraints to valid an enumeration?  There’s not one in the spec, and none of the tutorials I have demo this.

Suppose I have this DFDL:

<xsd:element name="DayOfTheWeek“…>

  <xsd:simpleType>

    <xsd:restriction base="xsd:string">

      <xsd:enumeration value="Mon" />

      <xsd:enumeration value="Tue" />

      <xsd:enumeration value="Wed" />

      …

    </xsd:restriction>

  </xsd:simpleType>

</xsd:element>

TIA
