What about this:

<xsl:stylesheet  version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:f="function"
 xmlns:map="http://www.w3.org/2005/xpath-functions/map">

 <xsl:output method="text"/>

     <!-- Test the two map functions -->
     <xsl:template match="/">
         <xsl:variable name="m" select="map{'Linda' := 'Rosie'}" />

         <xsl:variable name="m1" select="f:add-entry-to-map('Sally',
'Betsy', $m)" />
         <xsl:variable name="m2" select="f:add-entry-to-map('Barb',
'Sue', $m1)" />
         <xsl:variable name="m3" select="f:add-entry-to-map('Nadia',
'Valerie', $m2)" />
         <xsl:variable name="m4" select="f:add-entry-to-map('Faye',
'Carol', $m3)" />

         <xsl:sequence select="f:print-map($m4)" />
     </xsl:template>

     <xsl:function name="f:add-entry-to-map" as="map(xs:anyAtomicType,
item()*)">
         <xsl:param name="key" as="xs:string" />
         <xsl:param name="value" as="item()" />
         <xsl:param name="m" as="map(xs:anyAtomicType, item()*)" />

         <xsl:sequence select="map:new(($m, map:entry($key, $value)))" />
     </xsl:function>

     <xsl:function name="f:print-map" as="item()*">
         <xsl:param name="m" as="map(xs:anyAtomicType, item()*)" />

         <xsl:sequence select="map:keys($m) ! concat(., '-', map:get($m, .))"/>
     </xsl:function>
 </xsl:stylesheet>

Cheers,
