export: Explicitly allow empty NAMESPACE

Browse Source 
Modify argument handling in `HandleExportMode` to explicitly allow an
empty `NAMESPACE`. In practice, this was already the case because we
weren't actually checking for the parsing errors that would cause the
`NonEmpty` decoration to reject an empty value, but we want to be able
to do that going forward, and changing the behavior for `NAMESPACE`
would potentially break legitimate uses. (In particular, one of our unit
tests relies on the current behavior.)
