If I'd feel a sudden urge to request "erzgeb" I'd ask for prefix
"de" for various reasons akready stated here.  As I don't feel
this urge the point is moot.  Thomas' plan to wait for "sxu" and
later prove that sxu-erzgeb is linguistically dubious at best is
cute.

s/when/if/  The last draft I've seen proposes to register pseudo-
regions dg, ea, eu, ic, and more, excluding the relevant case uk.
