The following query…
db:open('factbook')/mondial/country/country
…will be rewritten to an empty sequence at compile time, because the country element has no country child elements.
country

db:open('factbook')/mondial/country/country[@population]
…and paths within predicates:
db:open('factbook')/mondial/country[country]
The optimizations could serve as preparatory step for #2069.
