@ATT
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.
