A "." used within a predicate always refers to the node for which the
(immediately containing) predicate is being evaluated.

You can expand this into an XQuery-like construct if it helps your
understanding:

select="for $x in child::*
        where exists(for $y in $x/child::*
                     where name($y)=$child and $y=$value
                     return $y)
        return $x"

$y here plays the role of "." in the inner predicate, while $x represents
the value of "." in the outer predicate.
