[Tagging] Binding numbers

[Bert -Araali- Van Opstal]

Seems a nice option. We all know, that addresses due to their numerous
local variants can be a very complicated matter.  What we have so far is
very solid. I propose to extend the examples in the wiki with confusing
or complicated challenges and how they can be viable and creatively
solved, like was done in the proposal page for the Vietnamese
addressing. So users, also the ones who don't contact any of our help or
communication channels find better guidance.

Greetings to all,

Bert Araali
