To quote the example from Jeni Tennison's post
<xsl:template match="/">
  <xsl:apply-templates select="r/a">
    <xsl:sort data-type="number" select="@at"/>
    <xsl:with-param name="p" select="position()"/>
  </xsl:apply-templates>
</xsl:template>

apply-templates will not change the context,
for-each on the other hand will create a new context

Can someone clarify the meaning of "position()" in apply-templates.

According to Michael's Kay's 4th edition,

"When <xsl:apply-templates> or <xsl:for-each> is called to process a
sequence of nodes, the nodes ar enumbers 1 to N in their sorted order,
and while each node is being processed. the context position is the
number assigned to that node."

But I found a 2001 post indicating that, within an
<xsl:apply-templates> instruction *itself* the context position is
just the context position of the current node (_not_ the nodes being
selected by the select attribute of <xsl:apply-templates>). That post
is here=http://www.stylusstudio.com/xsllist/200105/post90830.html

My question is "When the "number assigned to that node" (as referenced
in Kay) is considered the context position? :

A. In the predicate of the select attribute of the
<xsl:apply-templates> instruction?
B. In the select attribute of any <xsl:with-param> instructions inside
the <xsl:apply-templates> instruction?
C. In the body of the <xsl:template> called by the
<xsl:apply-templates> instruction?
