Let's say we have following XML document,

<X>
   <a>pass</a>
</X>

and it's validated by the following schema,

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
	
    <xs:element name="X">
       <xs:complexType>
	   <xs:sequence>
	      <xs:element name="a" type="xs:string"/>			  
	   </xs:sequence>
       </xs:complexType>
    </xs:element>
	
    <xs:simpleType name="STATUS">
       <xs:restriction base="xs:string">
	  <xs:enumeration value="pass"/>
	  <xs:enumeration value="fail"/>
       </xs:restriction>
    </xs:simpleType>
	
</xs:schema>

Now when we evaluate an expression like following (within the context of above XML and schema documents),

X/a castable as STATUS

then this expression evaluation should be aware of the simple type definition STATUS.

This is particularly useful in scenarios where we use XML Schema 1.1 assertions as follows,

<xs:element name="X">
   <xs:complexType>
      <xs:sequence>
         <xs:element name="a" type="xs:string"/>			  
      </xs:sequence>
      <xs:assert test="a castable as STATUS" />
   </xs:complexType>
</xs:element>

I've written a patch for this, and would be committing it asap along with a test case.

Reproducible: Always
