The following appears to work with the latest Saxon in an
XSLT v2 style sheet.
<xsl:for-each select="position()">
My take on this is that position() returns a number and that
number is then used in a sequence of one. Am I understanding
this correctly and should this be how all XSLT v2 processors behave?
Yes. It doesn't seem a very useful construct, but that's what it does. I can
imagine a use for
<xsl:for-each select="position()-1, position(), position()+1">
But wherever you can use a sequence of several numbers, you can also use a
sequence containing a single number.
