Can we go with this instead:

Description: Cornu-English
Description: Anglo-Cornish
Description: Cornish English

That's what we've done for the entire RFC 4646 and 5646 period. The 
single comma-separated Description field that presents alternative 
descriptions is now relegated to the grandfathered tags such as 
"zh-min-nan" (q.v.).
