If you have an expression of the form

//x[@y=$v]

then you can often improve performance by declaring a key

xsl:key name="k" match="x" use="@y"

and changing the expression to

key('k', $v)

But you won't get improved performance, or correct results, by shoving in
calls to key() where they don't make sense.
