Test Data Gone?

Steven, thanks for the reminder about that implementer's guide, I hope that
will become a full-fledged resource at some point. I haven't really
contributed to it because I feel like such a CLDR/ICU n00b even after
working with the data for almost 5 years. It's a document I would love to
read today as a CLDR implementer, but I don't feel qualified to contribute
to it. Surely the members of the ICU team have insight to share here?
