Hi Roger,
I think this would work better ...
<xsl:function name="f:add-entry-to-map" as="map(xs:string, item())">
<xsl:param name="key" as="xs:string" />
<xsl:param name="value" as="item()" />
<xsl:param name="m" as="map(xs:string, item())" />
<xsl:sequence select="map:new( ($m), map:entry($key, $value)))"
/>
</xsl:function>
.. as the map:new() function works on a sequence of maps. Refer to the
example in the spec, entitled "Example: Using a Map as an Index".
Faithfully,
Sean B. Durkin

Hi Folks,
Below is a stylesheet that implements two functions on maps:
1. Update an existing map with another key/value pair
2. Print the contents of a map
I'm mighty proud of these two functions.
But I'm willing to believe that there exists an even better
implementation.
Challenge: can you create a better implementation of these two
functions?
