Bug #2708
Updated by Michael Kay about 8 years ago
It is possible to export a stylesheet containing a constant map; however, such a stylesheet cannot be imported.
This does not happen when a map is written literally as, for example
<pre>
<xsl:sequence select="map{'a':5, 'b':6}"/>
</pre>
because such a map is exported as a sequence of calls on internal functions whose effect is to recreate the map.
It does happen, however, when the map is expressed by a call on parse-json() with a literal argument, for example
<pre>
<xsl:variable name="json">{'a':5, 'b':6}</xsl:variable>
<xsl:sequence select="parse-json($json)"/>
</pre>
Attempting to load this stylesheet produces the message
*SXPK0002: Cannot load expression with tag map*
