Allow to specify 0..0 occurrences for SLOT nodes

Description

Currently it is not possible to "remove" SLOTs from archetypes to generate an OPT with no SLOTs.

The use case for this is when the slots are not used, so the resulting OPT shouldn't include them.
Also, considering the OPT as the final result of the modeling process, it won't have extensions, so SLOTs are not needed on the OPT. If extensions are needed, that will be done at the OET level.
