I believe all listed imports must resolve to a valid YANG module in
order to parse a given YANG module successfully. This should be part
of the language definition.

What actually happens if a parser hits an unresolvable import is
implementation specific. Some implementations may choose to stop
immediately when they hit an unresolvable import while others may
choose to complain loudly and try to continue as far as they get.
