JFYI: In the following scenario, the result of MSXML .NET

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"

  <xsl:template match="/">
          <xsl:value-of select="count(//foo[name() = 'foo'][1])"/>

Which is to say, count all first-of-siblings named 'foo' at all levels of the document.

</xsl:template>

</xsl:stylesheet>

<?xml version="1.0"?>
<foo>
  <foo>
    <foo/>
    <foo/>
    <foo/>
  </foo>
</foo>

There are three points in the document at which there is a 'foo' amongst siblings.

Result of MSXML .NET:
<?xml version='1.0' encoding='utf-8' ?>
1

That is an incorrect result.

All the other processors return "3".

However, MSXML .NET returns "3", if we change the expression to
"count(//foo[1][1])".

That is also the count of all first siblings named 'foo' at all levels of the document.

p.s. an XPath expression very similar to the above is one of the trick questions in the XPath portion of my training class.
