Review comment:
This implementation parses and validates _lazily_ on the first
authentication attempt. With DataSourceRealm, I actually do not need an array
or a collection but only a proper SQL statement. Of course, that is built from
a parsed and validated (temporary) list (using `split()`...). However, I
validate requested attributes and emit log messages for every invalid
attribute. I can't do that in the setter, since `containerLog` is still null
when the setter is invoked while the component gets initialized. So I would end
with only parsing in the setter and still need to validate lazily on the first
authentication attempt.
