[xsl] Map duplicate handling differences

["Michael Mueller-Hillebrand michael.mueller-hillebrand@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hello Friday folks,

I have noticed that the duplicate handling when constructing maps is different
and I would like to understand the reason.

When using <xsl:map> with <xsl:map:entry> the transformer rejects duplicate
keys with a runtime error.

<xsl:variable name="pairsMap" as="map(xs:string, xs:string)">
    <xsl:map>
       <xsl:for-each select="tokenize($pairsString, ';')">
            <xsl:map-entry key="substring-before(., '=')"
select="substring-after(., '=')"/>
        </xsl:for-each>
    </xsl:map>
</xsl:variable>

When using map:merge() without any extra options it uses duplicates:use-first
(I learned I can turn on brejectb or buse-lastb or bcombineb):

<xsl:variable name="pairsMap" as="map(xs:string, xs:string)"
        select="map:merge(
            for $t in tokenize($pairsString, ';')
                return map:entry(substring-before($t, '='),
substring-after($t, '=')))"/>

Have I overlooked a way to define options in the xsl:map case?
Or is this a subtle way to get us to move to inline XPath?

Have a nice weekend,

- Michael
