  Errors are reported to System.err by Transformer with registered ErrorListener during:
  - transforming the invalid xml document by javax.xml.transform.Transformer.transform()
method (see test1.java below);
  - creating a Transformer object by javax.xml.transform.TransformerFactory methods from
the invalid source (see test2.java below).
  The javadoc reads:
  
  "public interface ErrorListener

   To provide customized error handling, implement this interface and use the
setErrorListener method to register an instance of the implmentation with the
Transformer. The Transformer then reports all errors and warnings through this
interface.
  If an application does not register an ErrorListener, errors are reported to
System.err.
  ..."

  This bug is found in jaxp-1.2.0-beta-b12-04_mar_2002 and and appears while running the
tests of the JAXP 1.2 TCK:

 api/javax_xml/transform/ErrorListener/index.html#FatalError[FatalError001]
 api/javax_xml/transform/Transformer/index.html#Transform[Transform002]
 api/javax_xml/transform/TransformerFactory/index.html#NewTemplates[NewTemplates002]
 api/javax_xml/transform/TransformerFactory/index.html#NewTransformer[NewTransformer003]

  This behaviour of the JAXP RI affects build of the JAXP TCK 1.2 - the messages about
fatal errors are written to the build log while the tests passed OK.
