Namespace problems

Hi,

I'm having some problems related to namespaces (I think).

The source file for the transformation:

<rdf:RDF xml:base="http://a.com/ontology" xmlns="http://a.com/ontology#"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xmlns:owl="http://www.w3.org/2002/07/owl#"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
...
<Products rdf:ID="id_9000.271151">
	<BelongsToSeries rdf:resource="#ids_Robusta"/>
	<has_Finishing rdf:resource="#idf_BrancoTexturado"/>
	<BelongsToCollection rdf:resource="#idc_CamasMesasCabeceira"/>
	<Reference
rdf:datatype="http://www.w3.org/2001/XMLSchema#string">9000.271151</Referenc
e>
	<Name rdf:datatype="http://www.w3.org/2001/XMLSchema#string">ESTANTE
ROBUSTA  66 BR</Name>
</Products>
...

On the xsl I'm trying to enter the Products element but with no sucess...

<xsl:stylesheet version="1.0" xmlns="http://a.com/ontology#"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:owl="http://www.w3.org/2002/07/owl#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xml:base="http://a.com/ontology" exclude-result-prefixes="rdf rdfs owl">

<xsl:output method="xml" indent="yes"/>

<xsl:template match="/">
 	<rdf:RDF xmlns="http://a.com/ontology#"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xmlns:owl="http://www.w3.org/2002/07/owl#" xml:base="http://a.com/ontology">
...
	<xsl:apply-templates/>

	</rdf:RDF>
</xsl:template>

<xsl:template match="Products">
	<xsl:element name="Product_class"/>
</xsl:template>


</xsl:stylesheet>


I can't create the Product_class element because the template is not being
applied... Why is it happening? What am I doing wrong? 

Can somebody help?

Thank you,

Regards,
Ricardo Saraiva.
