Bundling of Domain Names and DNAME

Actually it does not matter whether the final sigma is PVALID or not,
although I believe that it will be since both the .gr Registry and .cy
Registry have asked for it.
We have the same issue with the accent mark "tonos". Almost each word in
Greek has this accent mark in small letters but if you put it in capital
letters the mark is omitted, creating two different xn-- Punycode
translations for each word used as a domain name.
We Bundle domain names already because of this "tonos" and we face this
bundling issue since 2005 but we had put our hopes on the IDNA revision for
a better solution. Since this is not possible, we need the XNAME bundling
regardless of the final sigma in IDNA2008 situation.

The IDNAbis WG drafts have not been published as RFCs yet. Currently,
the drafts make Final Sigma (Unicode U+03C2) PVALID, but this issue is
currently being discussed in the WG.
