Why attributes are internal ?

[QM-OSchwab]

Hello,

Firstly congrats for your library, it's quite well designed and very convenient to use.
I forked it in order to be able to evaluate it in .NET 4.7.2.
My point is that I would like to inherit from some record types or create my own ones (for example my own Order record).

This is impossible because all the attributes are defined as internal.

Is there a justification for that ? Is there another mean to do what I need. ?

Bonus question : there is no mean to define a field as a component (Something like [LisComponent(4,2)] that would take the 2nd compoment of the 4th field ) ?

Drop the bonus question, I just stumbled upon AbstractLisSubRecord...
