Description:
I am using jaxp api in my xslt trandformation code and running with xalan 2.0.0.
I developed and then registered my own error listener with the
TransformerFactory and the Transformer. In some cases, I am finding that this
error listener is not getting called at all.

For example, in one case while testing the error listener getting called for
problems during xsl file compilation, my xsl file had a line <xsl:value-of
select = "/CxQuoteContainer/containerInfo/attribute/atomicValue[]"/>. In this
case, the following exception was thrown bypassing the error handler:
javax.xml.transform.TransformerException: java.lang.NullPointerException
        at org.apache.xalan.transformer.TransformerImpl.transformNode(Transforme
rImpl.java, Compiled Code)
        at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java
:2894)
        at java.lang.Thread.run(Thread.java:479)
The strange thing is that the above stack trace does not contain any entries
pointing to my code.

In another case, to test error listener with transformation errors, I added a
the specification <!DOCTYPE EOM_SLTC_ORDER> to my xml string without a
corresponding root element. There again the following errors were flagged, but
the registered listener was bypassed (and the transformation completed as it
should have):
[Error] :1:44: Document root element "CxQuoteContainer", must match DOCTYPE root
 "EOM_SLTC_ORDER".
[Error] :1:44: Element type "CxQuoteContainer" must be declared.
