SMT Technical Data - idShort for MainSection

[MMuellerMitsubishi]

In the Technical Data SMT there is the possibility to define Main Sections and Sub Sections.
As an example of a main section "Electrical" is mentioned as a value. Where shall this value be stored? The SMC doesn't have a field for a value.
So, I assume that the idShort of the MainSection should be "Electrical". But in the definition there is no placeholder for the idShort of the MainSection. The specification says I must name the SMC "MainSection{00}".
I think the idShort of the MainSection should also be changed to "{arbitrary}" as for the SME above. Then the SemanticID indicates that this SMS is a MainSection.
Same applies for the SubSection.
