EXSL's dyn:evaluate() and XALAN vs. xsl:use-attribute-

Hi,

As I don't really like mailinglists it was kind of hard for me do this step
but for my current problem
I can't find a proper answer elsewhere:

Suppose I have the following XML document:

...
<elemxy class="test1">Some content</elemxy>
...

And the following template snippet:

...
  <xsl:template match="elemxy">
	    <fo:block  xsl:use-attribute-sets="dyn:evaluate(@class)">
	    			<xsl:apply-templates/>
	    </fo:block> 
  </xsl:template>
...

Obviously I have several different class attributes (like test1 here) and
want
them to be the name of an attribute-set. This because: I'm generating the
attribute-sets dynamically
and attach them to the xsl stylesheet.

My question is now: Why is the above construct NOT working?
I'm using xalan-j_2_5_1 and my root element of the stylesheet looks like
this:

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:fo="http://www.w3.org/1999/XSL/Format"
                xmlns:xalan="http://xml.apache.org/xalan"
                xmlns:dyn="http://exslt.org/dynamic"
                extension-element-prefixes="dyn">

Xalan simply ignores the statement. When I replace the expression with 
a static name the proper attribute-set is used.
