Hi @erlemantos
could you please merge these DSL changes with the existing grammar documentation?

@MichaelGuenther @erlemantos What is the status of this Pull Request? It seems to be a single MD file but does not yet fit into our current documentation.

[erlemantos]

I've already updated the .md files for the DSL appendix. As to the tutorial that I wrote for the DSL updates, I don't know where to put that.

@erlemantos @MichaelGuenther
The improvement markdown has to be somewhat merged with the appendix of function block and datatype where each element is described in the table. At the moment the improvement MD is not referenced from anywhere, how can a user find it ?

[MichaelGuenther]

@erlemantos, @aedelmann,
I recognize two task:

• Updating the examples in the Model DSL Reference
  Please provide reasonable examples updated according to the DSL improvements.
• Updating the semantics in the Model DSL Reference
  Please provide information (sources) I can incorporate.

Regards
Michael

Hi @aedelmann , @MichaelGuenther

I just added some commits to fix the two points pointed out on Michael's comment:

1. Moved entity and enum to datatype appendix, as they should be in datatype.
2. Examples in the function block semantics that shows the improvements to the DSL
3. An entire new section of datatype appendix (Semantics) that expounds more on the
   datatype.
4. Modified the function block and datatype syntax to reflect improvements
   to the DSL
