The WKN is only unique inside the german markets. If you also have a
french bank, they might send the SEDOL instead.

But ISIN would be unique. It is "DE"<WKN><checkdigit>.

I wonder if we should at some point separate ISIN as gloal unique
identifier from the catch-all field "ISIN, CUSIP or other identifier".

Namespace+Symbol is the current unique identifier.
ISIN would be unique while NSINs like WKN have the implicit assumption
all securities are emitted in the same country.
