If it doesn't have 1994 as a prefix (or vice versa), the subtags are
mutually exclusive (with a SHOULD NOT). See section 2.2.5:
Most variants that share a prefix are mutually exclusive. For example,
the German orthographic variations '1996' and '1901' SHOULD NOT be used
in the same tag, as they represent the dates of different spelling
reforms. A variant that can meaningfully be used in combination with
another variant SHOULD include a 'Prefix' field in its registry record
that lists that other variant. For example, if another German variant
'example' were created that made sense to use with '1996', then
'example' should include two Prefix fields: "de" and "de-1996".
Circular prefix references are to be forbidden by 4646bis (and by policy
they should be now).
