The method

     javax.xml.validation.TypeInfoProvider.getElementTypeInfo()

does not throw IllegalStateException in case when the method is called from ContentHandler
methods that differ from the method startElement(). The method getElementTypeInfo() should
throw IllegalStateException according to the javadoc:

    public abstract org.w3c.dom.TypeInfo getElementTypeInfo()
    ...
    The method may only be called by the startElement event of the ContentHandler that the
    application sets to the ValidatorHandler.
    ...
    Throws:
     java.lang.IllegalStateException - If this method is called from other ContentHandler
     methods.

The bug affects new JCK1.5 tests (not integrated yet):

  api/javax_xml/validation/TypeInfoProvider/index.html#GetElementTypeInfo[GetElementTypeInfo002]
  api/javax_xml/validation/TypeInfoProvider/index.html#GetElementTypeInfo[GetElementTypeInfo003]
  api/javax_xml/validation/TypeInfoProvider/index.html#GetElementTypeInfo[GetElementTypeInfo004]
  api/javax_xml/validation/TypeInfoProvider/index.html#GetElementTypeInfo[GetElementTypeInfo005]
  api/javax_xml/validation/TypeInfoProvider/index.html#GetElementTypeInfo[GetElementTypeInfo006]

The following test fails running on JDK 1.5.0-beta-b31.
