A few questions:

Would it not be preferable to invert the choose as in

<xsl:for-each select="(  . . .)">
           <xsl:when test=". instance of xs:anyAtomicType">
               <xsl:value-of select="."/>
               <xsl:apply-templates select="$foo,." />

especially since node() will also return text nodes that should probably be atomized ?

Also, wouldn't castable as be preferable to instance of, in this case ?
If so, might one want to separate strings, boolean, numbers and integers, as in

 <xsl:when test=". instance of xs:integer"> ... </when>
 <xsl:when test=". instance of number()"> ... </when>
 <xsl:when test=". instance of xs:boolean"> ... </when>
 <xsl:when test=". castable as xs:integer"> ... </when>
 <xsl:when test=". castable as number()"> ... </when>
 <xsl:when test=". castable as xs:boolean"> ... </when>
 <xsl:when test=". castable as xs:string"> ... </when>
 <xsl:otherwise><xsl:apply-templates select="$foo,." /></xsl:otherwise>


What would be the best way to do this ?

4. As for the use cases, aren't there more than might seem at first, especially where dynamic evaluation (ex: saxon:eval()) is used?




David Carlisle a C)crit :
a safer way is to use a global param, this prevents a static type error
(as the system can not know that you will not pass in a node) but if you
never do pass in a value then teh run time behaviour is as you wish:

<xsl:stylesheet version="2.0" xmlns:xsl="";>
<xsl:param name="foo" select="()"/>
<xsl:template name="x">
<xsl:for-each select="(1, 2, 3)">
            <xsl:when test=". instance of node()">
                <xsl:apply-templates select="$foo,." />
                <xsl:value-of select="."/>

$ saxon9 -it x stst.xsl
<?xml version="1.0" encoding="UTF-8"?>123
