Positional predicate written the long way

foo[1] means foo[position() = 1], and foo[last()] means foo[position() = last()]. Two spellings of one selection hide each other from a search, so keep the bare number, the idiom XSLT uses.

Incorrect:

<xsl:value-of select="item[position() = 1]"/>
<xsl:apply-templates select="row[position() = last()]"/>
<xsl:value-of select="cell[position() eq last()]"/>

Correct:

<xsl:value-of select="item[1]"/>
<xsl:apply-templates select="row[last()]"/>
<xsl:value-of select="cell[last()]"/>

Either operand order is flagged, with = or eq. A predicate that asks more, such as [position() = 1 and @current] or [position() > 1], keeps its position().
