Have you considered encouraging the Welsh linguists to work with the CLDR directly? Quite a number of such organizations contribute data directly to the CLDR. Please don't create yet another divergent process.
This is a sore point. As well as asking the Bedwyr Language Centre, who tell me that they are the 'official' contributors to CLDR, to comment on the principals of localising foreign proper nouns to Welsh for CLDR, I have also asked them to contribute terms and vote on those already contributed by others. I have deliberately held off from voting myself where the term to be adopted is not obvious, to allow them to take the lead in localising. I expect, however, to be waiting a long time, if past experience is anything to go by, before they can do anything with this, since their time and resources are heavily committed on all sorts of things. I intended to convey my cautious approach to the question of standardisation in my post above and am sorry that that was not clearly stated.
At the same time there is nothing controversial about the word 'Llydaweg', meaning 'Breton language', which has been around for hundreds of years, and no-one needs a language specialist to rubber stamp it. It would be nice to be able to have 'Llydaweg' in a database created here, for use here until it is superceded by the CLDR term, whenever that may become available. Whether that is practical is a matter for the developers here to address.
As it stands 'Llydaweg' is the unopposed entry. It has the status of 'contributed', but it certainly doesn't need 8 votes to be 'in CLDR' as things stand. It will show up as "<language type="br" draft="contributed">Llydaweg</language>" and twn (and other CLDR consumers) can decide whether "contributed" is better than nothing.
You said that you held off on voting, did you at least enter the terms? Because, the time for submitting data has now passed in most cases. What you can (could) have done is to enter an option, and then change your vote back to n/o (no opinion)- that puts an entry in but doesn't yet vote for it.
Thanks for participating, and please watch for a mass e-mail soon about the vetting phase.
