Re: [xsl] Map construction

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Alernatively, use the xsl:map and xsl:map-entry instructions. Unlike map:merge
this doesn't allow any control over handling of duplicates (though we're
adding that as a Saxon extension in the next release).

        <xsl:map>
>>     <xsl:map:entry key="'key1'" select="'val11','val12'"/>

etc

produces a single entry map. $myMap as written has type map(*)+ - a sequence
of single-entry maps. Use the $options second argument of map:merge() to
control behaviour when duplicate keys are detected...
