Mike Beckerle commented on DAFFODIL-1861:
-----------------------------------------
We don't intern the QName objects. They're immutable. There's no reason to ever
have more than one instance for a given QName.
Since they are used for lookups at runtime, we should intern them and always
use the same object instance.
This may save space, and may improve performance. Whether the improvement is
measurable is unclear, but it cannot hurt.
