Problems with value-of and extension function

           Summary: Problems with value-of and extension function
           Product: XalanJ2
           Version: 2.3
          Platform: PC
               URL: http://www.jayw.com/downloads/xalanbug.jar
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other

I am using a Java extension function which takes a NodeIterator and returns a
string - something like <xsl:value-of select="ns:lowercase($foo)"/> where if foo
was defined in a simple fashion like <xsl:variable name="foo"
select="id(@idref)/@name"/> it will work, but
<xsl:variable name="foo"><xsl:value-of
select="id(@idref)/@name"/></xsl:variable> doesn't work.  This used to work with
an older version of Xalan (I'm not sure which), but now I can't get it to work
with 2.2.0 or 2.3.D1.  Sometimes I get back a null string from my extension
function, sometimes I get a NPE in org.apache.xpath.objects.XRTreeFrag.

I even have a line in one template like

<xsl:value-of select="$foo"/>Ok = <xsl:value-of select="ns:lowercase($foo)"/>Not Ok 

that generates output FooOk = NullNotOk.

I put an input file (XML) a stylesheet (XSL) and the extensions function into
the jar shown above.
