It's misleading to single out specific expressions. It's a general
feature of xpath that if a system can deduce that it has evaluated the
only possible non-error value, it may (or may not) return that value
rather than have to evaluate an arbitarily large mount of data to check
for errors. So more or less any xpath expression may or may not generate
an error depending on processor behaviour.

they are not functions but node tests, and the second two may be used in
all processors not just schema-aware one, in their no or one argument forms.
