Title: The term 'Dutch' is wrong!

The term 'Dutch' is wrong! This is a postal code from The Netherlands, not 'Dutch'!
'Dutch' is NOT a country but a language which is spoken in different countries (with different forms of postal codes).
As such, please do not use such a regexp if you know your users speak 'Dutch'. Their postal code might be quite different!

This is too simple: letter combinations SS, SD and SA are not allowed for histiric reasons.
Title: Do not use *

* means 0, 1 or more times, so 3 spaces would also match. It should be a ?, indicating 0 or 1 time
