Hi, Ralf:

I've just replied a minute ago to this email in another previous
email, but I paste here again my opinion on this issue:

"Although I answered to this before, I would add that having one single
name in several nodes, with 1, 2, 3... or A, B, C... or I, II, III...
added to the end to differentiate them is quite common in many
countries in Africa. You can find many of them in Central African
Republic or Nigeria, as just two examples. I again would leave all
those nodes separated as they are, and not condense them in one. I
can't assure you that they are automatically produced, but it could
very likely not be the case."

Cheers,

Rafael.
