Limitations: ISO standard defines some restrictions about where to use
fractional numbers and which component and format combinations are
allowed. This _base implementation ignores all those restrictions and
returns something when it is able to find all necessary components.
In detail:
it does not check, whether only the last component has fractions.
it allows weeks specified with all other combinations
