Of course they are legal. Each predicate is is a filter that is applied to
the node-set that remains after applying the previous filters. For filters
that don't depend on position, multiple filters are equivalent to "and", but
for positional filters, the meaning is different, because position() and
last() refer to position among the nodes that remain after previous filters.
