[xslt] unparsed-entity-uri bug?

Hi Daniel

I've been using xsltproc and I think that is an excellent XSLT processor.
I was using xsltproc and I think I found a bug. 

The element graphic is defined in the DTD as:

<!ELEMENT graphic         EMPTY                                   >
<!ATTLIST graphic
                 figname  ENTITY                      #REQUIRED
                 scale    CDATA                       "100"       >


where figname attribute is an entity. In my XML document I use this graphic
element:

<graphic figname="SIMPLEGRAPH"/>

where SIMPLEGRAPH is the entity:

<!ENTITY SIMPLEGRAPH SYSTEM "simpleg.eps" NDATA eps>

There is an xslt that transforms this XML document in a HTML document. The
statement that uses @figname is:

<xsl:when test="unparsed-entity-uri(@figname)">

When I use xsltproc, I got this error:

unparsed-entity-uri() : invalid arg expecting a string

Hope this helps.
Best wishes
