An element node is supposed to inherit the namespace of its parent. But one 
of mine is not inheriting.

If I declare

<xsl:stylesheet 
xmlns:cm="urn:schemas-Professional-Plug-in:P2:ClipMetadata:v3.0">

then I should be able to prefix any node reference with "cm:" For example,

<xsl:value-of select="cm:P2Main/cm:ClipName" />

And, indeed, that does work in every parser I've tested, except... the Xalan 
parser used by FileMaker is complaining 

"XML parsing error: Attribute Œxmlns:cm¹ is not declared for element 
ŒFMPXMLRESULT².

But it is declared--in the very first line of the XSLT document!

 The complaining element lives in this template

<xsl:template match="/cm:P2Main/cm:ClipContent">
		<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
			<ERRORCODE>0</ERRORCODE>
			<PRODUCT BUILD="07/1/2006" NAME="FileMaker Pro" VERSION="8.0v1" />
		
	<RESULTSET>
				<xsl:attribute name="FOUND">
					<xsl:value-of select="14" />
				</xsl:attribute>
				<xsl:call-template name="records" />
</RESULTSET>

	</FMPXMLRESULT>

I have tried to insert that xmlns:cm declaration everywhere in the document, 
but FileMaker still keeps complaining that it is an undeclared attribute.

Any ideas?
