Reuse of properties in several submodels

[empwilli]

In [If the same properties are used in several submodels, shall they also be entered several times or shall they be referenced?](https://github.com/admin-shell-io/questions-and-answers?tab=readme-ov-file#id5) ist says:

Submodels shall be as independent as possible so that they can be changed and developed separately. Consequently, the same properties shall be copied to another submodel and references shall not be used in such case. The concept description referenced in semanticId, however, should be the same.

However, with the introduction (and use, e.g. in Digital Nameplate 3.0) of DropIns (see also "Guideline: How to Create a Submodel Template Specification"), the idea of definition and reuse, even across SM boundaries, is promoted.

In my opinion, this section should either be removed, or mention DropIns as a mechanism to realize reuse. In the latter case, it may make some suggestions when DropIns are more suitable and when SMTs should provide individual definitions.

The answer to this question was given a long time ago (over 5 years ago) and can now be considered outdated.

I completely agree that the answer should be revised and the concept of DropIns should be included in the answer.

Please feel free to create a PR with an updated answer.
