Err, correct me if I am wrong, but doesn't the 'preceding' axis include the
ancestors as well?
I would have guessed that the 'equivalent' would have been:
count(self::menu)+count(preceding::menu)
(apart from the zero-count case mentioned below)
Cheers,

And the question is: Is this XPath expression
count(./ancestor-or-self::menu)+count(./preceding::menu)
equivalent to this XSL expression?
<xsl:variable name="position">
<xsl:number level='any' count="menu"/>
</xsl:variable>
Almost. xsl:number will never return 0, but the XPath expression might. Take
a look at the XSLT 2.0 spec which defines xsl:number in terms of equivalent
XPath expressions.
