If the Prefix for 'pahawh2' in the Registry is "mww", users can write either "mww-pahawh2" or "mww-Hmng-pahawh2" with equal conformity to BCP 47. If the Prefix is "mww-Hmng", then using "mww" alone before the variant (i.e. "mww-pahawh2") would be regarded as valid, but less appropriate or suitable. Prefix values should be as restrictive as necessary to encourage good usage, _and no more so_. -- Doug Ewell | Thornton, CO, US | ewellic.org
