[xsl] document() function - unknown protocol

[Jim Nachlin <jnachlin@xxxxxxxxxxx>]

Hi List,

I hope that this is an appropriate question for this list.

In trying to process an RDF foaf document [1] using the
stylesheet [2], the processor, which is members of the
javax.xml.transform package, gives an error which tells me that
the protocol "arg" is unknown in this statement:

<xsl:when test="document('arg:/ifp')/*/*/*">
  <xsl:variable name="ifp">
    <xsl:copy-of select="document('arg:/ifp')/*[1]/*[1]/*[1]"/>
  </xsl:variable>
  <xsl:apply-templates mode="output"  ...   />
</xsl:when>

or

<xsl:variable name="def"
 select="document('arg:/schema')/ns/schema[@ns=$ns]/rdf:RDF/*[@rdf:about=$this or @rdf:ID=$name or @ID=$name]"/>

and in several other places.

In looking over the documentation on document(), there is no
mention of a protocol "arg" or what this could possibly be.  It
seems that the stylesheet is trying to refer to one of the
namespace URIs.

Thanks in advance for helping an XSL noob.
