Base64 is preferred to HEX because it yields a smaller encoding, but if we
further encode the Base64 encoded value in HEX we end up with a larger
encoding and with an application that is unnecessarily larger and more
complex than if HEX alone or Base64 alone were used.  Since XER and CXER
do not currently support Base64, the solution that yields the smallest
encoding and simplest application is HEX.

This double encoding in Base64 and HEX is a poor solution.  I see no
benefit to it.
