    PART C: definition of literal result elements
    
    There are three ways to define the literal result elements
    permissible in a stylesheet.
    
    (a) do nothing. This allows any element to be used as a literal
        result element, provided it is not in the XSLT namespace
    
    (b) declare all permitted literal result elements as members
        of the xsl:literal-result-element substitution group
        
    (c) redefine the model group xsl:result-elements to accommodate
        all permitted literal result elements.
        
    Literal result elements are allowed to take certain attributes
    in the XSLT namespace. These are defined in the attribute group
    literal-result-element-attributes, which can be included in the
    definition of any literal result element.

  <xs:annotation>
    <xs:documentation>
      A QName.
      This schema does not use the built-in type xs:QName, but rather defines its own
      QName type. Although xs:QName would define the correct validation on these attributes,
      a schema processor would expand unprefixed QNames incorrectly when constructing the PSVI,
      because (as defined in XML Schema errata) an unprefixed xs:QName is assumed to be in
      the default namespace, which is not the correct assumption for XSLT.
      The data type is defined as a restriction of the built-in type Name, restricted
      so that it can only contain one colon which must not be the first or last character.
