How to pass dynamic separator in key XSLT1.0

How to pass dynamic separator in , here i passed '|' as static , when i declare variable in xsl and used this place it gives error.

<xsl:variable name="separator" select="'|'"/>
<xsl:key name="key-before" match="result" use="substring-before(Store, $separator)"/>

input XML

<?xml version="1.0" encoding="iso-8859-1"?>
<results>
    <result>
        <Store>0180|1</Store>
    </result>
    <result>
        <Store>0180|2</Store>
    </result>
    <result>
        <Store>0181</Store>
    </result>
    <result>
        <Store>0183</Store>
    </result>
    <result>
        <Store>abc</Store>
    </result>
    <result>
        <Store>def</Store>
    </result>
    <result>
        <Store>0181|2</Store>
    </result>
    <result>
        <Store>0180|3</Store>
    </result>
    <result>
        <Store>0181|1</Store>
    </result>


</results>

What you ask for is not possible (in XSLT 1.0). Neither the match nor the use attribute of xsl:key can contain a reference to a variable.
