I wored out the XSLT Extension stuff, so Now my test transform looks like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan" xmlns:exslt="http://exslt.org/common" xmlns:dap="http://xml.opendap.org/ns/DAP/3.2#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" > <xsl:output method='xml' version='1.0' encoding='UTF-8' indent='yes'/>

<xsl:variable name="dummy"> <xsl:element name="att:dummy" namespace="{/dap:Dataset/@base}/ att#"/> </xsl:variable>

<xsl:template match="dap:Dataset" > <rdf:RDF> <xsl:copy-of select="exslt:node-set($dummy)// namespace::*"/> <xsl:apply-templates /> </rdf:RDF>

</xsl:template>

<xsl:template match="dap:Attribute" > <xsl:element name="{@name}" namespace="{/dap:Dataset/@base}/ att#"><xsl:value-of select="." /></xsl:element> </xsl:template>

</xsl:stylesheet>

And I get this error:

ERROR: 'com.sun.org.apache.xalan.internal.xsltc.TransletException: org.jdom.IllegalAddException: The namespace xmlns="http://base.document/att# " could not be added as a namespace to "rdf:RDF": The namespace prefix "" collides with an additional namespace declared by the element' org.jdom.transform.XSLTransformException: Could not perform transformation: com.sun.org.apache.xalan.internal.xsltc.TransletException: com.sun.org.apache.xalan.internal.xsltc.TransletException: org.jdom.IllegalAddException: The namespace xmlns="http://base.document/att# " could not be added as a namespace to "rdf:RDF": The namespace prefix "" collides with an additional namespace declared by the element

Which seemed odd until I dump out my dummy element:

<xsl:copy-of select="$dummy"/>

Which produces:

<dummy xmlns="http://base.document/att#" />

So despite the fact that I assigned a namespace prefix when I created $dummy, the XSLT processor appears to ignore it.

I don't understand how to do this thing with node-set. When I try this:

<xsl:variable name="dummy"> <xsl:element name="att:dummy" namespace="{/dap:Dataset/@base}/ att#"/> </xsl:variable>

<xsl:template match="dap:Dataset" > <rdf:RDF> <xsl:copy-of select="exslt:node-set($dummy)// namespace::*"/> <xsl:apply-templates /> </rdf:RDF> </xsl:template>

I get a "Namespace prefix 'exslt' is undeclared." error when I compile the stylesheet. Which isn't surprising, since it is missing and I suspect the crux of this trick is in setting the prefix correctly.
