<DD>Notify a message written using the <code>xsl:message</code> instruction
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>content</CODE> - a document node representing the message content. Note that the output of
<code>xsl:message</code> is always an XML document node. It can be flattened to obtain the
string value if required by calling <code>getStringValue()</code>.<DD><CODE>terminate</CODE> - Set to true if <code>terminate="yes"</code> was specified or to false otherwise.
The message listener does not need to take any special action based on this parameter, but the information
is available if required. If <code>terminate="yes"</code> was specified, then the transformation will abort
with an exception immediately on return from this callback.<DD><CODE>locator</CODE> - an object that contains the location of the <code>xsl:message</code> instruction in the
stylesheet that caused this message to be output. This provides access to the URI of the stylesheet module
and the line number of the <code>xsl:message</code> instruction.</DL>
