Representing Additional Types of Flags

[Doug Ewell]

Also posted as formal feedback to the PRI:

6. What is the policy on generating flag tags with unicode_region_subtag
values corresponding to private-use BCP 47 subtags, other than those
given special semantics by CLDR? Are they invalid or merely discouraged?
Should tools allow users to create such a tag? Is there any provision
for a "private agreement," similar to that defined in Unicode for PUA
usage?
