APAR status

• Closed as program error.

Error description

• If an XSLT stylesheet has a document type definition (DTD) that
  contains entity declarations, the XML parser that processes
  the stylesheet will report errors of the form "Element type
  'xsl:stylesheet' must be declared."
  The processor continues processing the stylesheet correctly.

  * PROBLEM DESCRIPTION: Errors are reported for an XSLT         *
  *                      stylesheet that has a document type     *
  *                      definition (DTD) that contains only     *

  * RECOMMENDATION:  Install a fix pack that contains this APAR. *
  ****************************************************************
  The XSLT processor configures the XML parser it uses to parse
  an XSLT stylesheet with a feature known as "dynamic
  validation" enabled.  With the dynamic validation feature
  enabled, the parser will only report validation errors if the
  stylesheet has a DTD, but the parser cannot find declarations
  for the elements in the stylesheet in that DTD.  The processor
  will correctly process the stylesheet, despite the error
  messages that the parser reports.
  
  The processor enables the dynamic validation feature on the
  parser along with schema validation.  If the stylesheet
  is actually an input document that contains an xml-stylesheet
  processing instruction, and that processing instruction uses a
  URI fragment to refer to a stylesheet that is embedded within
  the input document, the processor can resolve that URI
  fragment using any attributes of type ID that are in the input
  document.
  

Problem conclusion

• The problem was resolved by having the XSLT processor connect
  the XML parser it uses to process the stylesheet to a separate
  Validator component.  The Validator component attempts to
  validate the stylesheet against any DTD or schema, so that
  attributes that are of type ID can be identified for use in
  resolving any URI reference in an xml-stylesheet processing
  instruction.  The errors reported by this Validator are
  ignored, and not reported to the user, as they are only
  distracting to the user and not useful.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.1.  Please refer to the Recommended Updates
