implicit existential quantification
is the phrase to look for. I think in the spec it's actually now,

General comparisons are existentially quantified comparisons that may

comparison that does not raise an error is always true or false.

This is the XPath 3.1 prose, but this is also in XPath 2; in XPath 1 =
works the same way but on node sets, so you can write
	boy[sock = 'blue']
and get true of false regardless of how many sock elements there are.
Or,
	//table[.//td > 600]
to find any table with one or more td elements having a numeric value
greater than 600.
