I thought I was benefiting from the description of the pattern-property
in the RIFSC YAML file. But yes anyway, it seems like it needs some
description here as the dependency does not appear in this file.
I picked 3 as a maxItems for our ST needs, I'll give it some more
thought when coming back with something clearer.
I will change that in V2, thank you for pointing that out.
Best regards,
Gatien
