Model Validation Rule DWF_DS_15 and DWF_DS_16

Hello everyone,

I’m looking into the various model validation rules of Capella these days. Can anyone tell me what’s the meaning of rule DWF_DS_15 and DWF_DS_16? They are in “Capella->Well-formedness->Scenarios”.
DWF_DS_15: This rule checks that a shared data READ is within an execution.
DWF_DS_16: This rule checks the refinement needed for decomposed Logical components.

Thanks in advance!
