id() doesn't work!?

Hello,

When I run this stylesheet:

--------------------------- cut --------------------------------------
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet
    version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:lxslt="http://xml.apache.org/xslt"
    xmlns:exsl="http://exslt.org/common"
    xmlns:date="http://exslt.org/dates-and-times"
        extension-element-prefixes="exsl date"
>
<xsl:import href="page2html.xsl" />
<xsl:import href="functions/date.date.template.xsl" />
<xsl:output
    method="html" indent="no" encoding="iso-8859-1"
/>

<xsl:param name="ref">char-usagi</xsl:param>

<xsl:template match="/">
    <xsl:message>ref=<xsl:value-of select="$ref"/></xsl:message>
    <xsl:message>id1=<xsl:value-of select="//character[@id = $ref]/name"/></xsl:
message>
    <xsl:message>id2=<xsl:value-of select="id($ref)/name"/></xsl:message>
</xsl:template>

</xsl:stylesheet>
--------------------------- cut --------------------------------------

on this document:

--------------------------- cut --------------------------------------
<?xml version="1.0" encoding="iso-8859-1"?>
<synopses>
    <character id="char-usagi">
            <name>Miyamoto</name>
        </character>
</synopses>
--------------------------- cut --------------------------------------

then I get:

    ref=char-usagi
    id1=Miyamoto
    id2=

but I should get:

    ref=char-usagi
    id1=Miyamoto
    id2=Miyamoto

Version-Info:

Using libxml 20422, libxslt 10018 and libexslt 709
xsltproc was compiled against libxml 20422, libxslt 10018 and libexslt 709
libxslt 10018 was compiled against libxml 20422
libexslt 709 was compiled against libxml 20422

After some hours of try&error, I finally found why it doesn't
work: If the elements are not declared in a DTD, then id() doesn't
work. DUH.

Can someone please add a check to xsltproc which prints a warning if
id() is used in a document which is only well-formed or, even better,
if the document doesn't have any attributes with are declared as
ID attributes.

Thanks,
