Inside a predicate position() changes it's meaning. So you probably want
something like:

> <xsl:for-each select="$set">
      <xsl:variable name="pos" select="position()"/>
>     <xsl:text>Iteration #</xsl:text>
>     <xsl:value-of select="$pos"/>
>     <xsl:text> is '</xsl:text>
>     <xsl:value-of select="$set[$pos]"/>
>     <xsl:text>'&#10;</xsl:text>
> </xsl:for-each>

Though it's still rather nonsensical since $set[$pos] is the same as
".", perhaps you wanted to index into some other node-set, e.g.
$set2[$pos]?
