BCP 47, Section 4.1 ("Choice of Language Tag"), bullet point 6 has this
to say about reordering variant subtags:
"If a variant lists a second variant in one of its 'Prefix' fields, the
first variant SHOULD appear directly after the second variant in any
language tag where both occur. General purpose variants (those with no
'Prefix' fields at all) SHOULD appear after any other variant subtags.
Order any remaining variants by placing the most significant subtag
first. If none of the subtags is more significant or no relationship
can be determined, alphabetize the subtags."
What does the word "significant" mean in this context?
I note that this section is not normative with regard to conformance or
canonical form; it's something for humans to consider, not necessarily
for software to enforce. But I'm curious.
