It truely doesn't matter as these are opaque string, carrying no other information. (yes?) We just have to make sure they are unique. So if you have a preference, go with it.

The existing rules specified in the Identifier spec still apply. It's just when we use the components from the IVOA ID in this specific case, certain characters that are illegal in the xs:ID context must be translated.
Since multiple characters can get mapped into two characters, this convention is not fail-safe.
