  <!--
    The 'switch' is not defined here, only its attributes are, alongside
    the test attributes that may be used to express conditions on subtrees.
    The reason for this is because 'switch' has a content model that is
    equivalent to the content model of the element that contains it. It is
    therefore defined everywhere that it is allowable.
