Missing region identifiers in Wiki

The Wiki currently documents 21 region identifiers. Yet there are plenty more to choose from.

Comparing the identifiers from the Wiki and the region names on Azure, it seems as if the identifiers can be derived by removing the spaces and changing everything to lowercase. So "Switzerland North" would be switzerlandnorth.
Is that correct? If yes, you should add that explanation to the Wiki. If no, what are the identifiers for other regions?
