Hello,

is it legal to construct a map this way :
<xsl:variable name="myMap" as="map(xs:string,xs:string+)">
B  <xsl:sequence select="map:entry('key1', ('val11','val12'))"/>
B  <xsl:sequence select="map:entry('key2', ('val21','val22'))"/>
</xsl:variable>
Or should I construct a sequence of map:entry, and then apply map:merge on that sequence ?

You should use map:merge(map(*)*) on a sequence of maps - map:entry() 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...


Thanks in advance,
Christophe
