I know that when I run an XSLT transform from the DOS command line,
the contents of <xsl:message> goes to the command line.

If I invoke an XSLT transform using, say, a Java program, where does
the <xsl:message> content go? If there are multiple <xsl:message>
elements, does their content all go to the same place? Where? Is it
the same for every XSLT processor?

.NET's XslCompiledTransform has this event
http://msdn.microsoft.com/en-us/library/system.xml.xsl.xsltargumentlist.xsltmessageencountered(v=VS.90).aspx

What happens to the in-memory result tree when the XSLT processor
encounters an <xsl:message terminate="yes"> element?
