   Calling this function with defaulted arguments rMaybeFileHdl = Link() and
   bCheckFileExists = true often leads to results that are not intended:
   Whenever the given rTheBaseURIRef is a file URL, the given rTheRelURIRef is
   relative, and rTheRelURIRef could also be smart-parsed as a non-file URL
   (e.g., the relative URL "foo/bar" can be smart-parsed as "http://foo/bar"),
   then SmartRel2Abs called with rMaybeFileHdl = Link() and bCheckFileExists =
   true returns the non-file URL interpretation.  To avoid this, either pass
   some non-null rMaybeFileHdl if you want to check generated file URLs for
   existence (see URIHelper::GetMaybeFileHdl), or use bCheckFileExists = false
   if you want to generate file URLs without checking for their existence.
