Xquery ampersand error

Hi all,
I am implementing a search page in my application, which queries an external
exist db. I want to know is there a way to use the &= operator that is used
in some of the sandbox examples that come with exist? (As i want to be able
to search a node of the xml document by keyword)

Currently the xslt processor to build the query I send to exist looks like
this:
<!-- Dynamically build query -->
        <p:processor name="oxf:xslt">
            <p:input name="data" href="#instance"/>
            <p:input name="config">
                <xdb:query collection="/db" create-collection="true"
xsl:version="2.0">
                    xquery version "1.0";
                    <document-infos>
                    {  
                        for $d in /document-info[.//jelr:subject &amp;=
'<xsl:value-of select="instance//subject"/>']
                        order by xs:dateTime($d/document-date) descending
                        return $d 
                    }
                 </document-infos>
                </xdb:query>
            </p:input>
            <p:output name="data" id="query"/>
        </p:processor>

This is throwing an XmlRpcException : unexpected char: '&' 

I have also tried enclosing &= in an xsl text element as follows:
<xsl:text disable-output-escaping="yes">&=</xsl:text> but this doesnt work..

Any ideas?

Fiona,
    To get around this I normally assign & to a variable

<xsl:variable name="amp">&</xsl:variable>

then use value-of to apply it

<xsl:value-of select="$amp"/>

This might work in you case, otherwise you will have to double escape it
with

&amp;
