I use another guideline, which is to use xsl:for-each when you use the
position() or last() function in the 'template' (the content of the
xsl:for-each or xsl:template).

The reason for this is that the result of the position()/last()
functions for a particular node are completely dependant on the nodes
that are selected for processing. I think keeping the location path
that selects the nodes and the use of the position()/last() functions
close together (as you do with an xsl:for-each) makes the stylesheet
easier to understand and maintain than when the location path and the
function call are in completely different parts of the stylesheet.
