RE: Problem with types derived from mixed complex types

This is how it's done in the schema for XSLT 2.0:

<xs:complexType name="versioned-element-type" mixed="true">
  <xs:complexContent>
    <xs:extension base="xsl:generic-element-type">    
      <xs:attribute name="version" type="xs:decimal" use="optional"/>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

<xs:complexType name="text-element-base-type">
  <xs:simpleContent>
    <xs:restriction base="xsl:versioned-element-type">
      <xs:simpleType>
        <xs:restriction base="xs:string"/>
      </xs:simpleType>
      <xs:anyAttribute namespace="##other" processContents="lax"/>
    </xs:restriction>
  </xs:simpleContent>
</xs:complexType>

<xs:element name="text" substitutionGroup="xsl:instruction">
  <xs:complexType>
    <xs:simpleContent>
      <xs:extension base="xsl:text-element-base-type">
        <xs:attribute name="disable-output-escaping" type="xsl:yes-or-no"
default="no"/>
      </xs:extension>
    </xs:simpleContent>
  </xs:complexType>
</xs:element> 

This is doing what the post you refer to says isn't allowed: deriving
simpleContent by restriction from complexContent. It seems to work!
