I would claim that you cannot register de-42-US-314159, not because
of the -US-, but because of the -42-. RFC 3066 says:
The following rules apply to the second subtag:
- All 2-letter subtags are interpreted as ISO 3166 alpha-2 country
codes from [ISO 3166], or subsequently assigned by the ISO 3166
maintenance agency or governing standardization bodies, denoting
the area to which this language variant relates.
- Tags with second subtags of 3 to 8 letters may be registered with
IANA, according to the rules in chapter 5 of this document.
- Tags with 1-letter second subtags may not be assigned except after
revision of this standard.
The question is whether 'letter' in the first clause means 'alphabetic,
but not digits', or whether it means 'any letter, including digits'.
Given the overall structure, it seems very clear to me that the second
interpretation makes much more sense.
