+# OpenMP dialect: Fortran descriptor type mapping for offload
+
+The descriptor mapping for OpenMP currently works differently to the planned direction for OpenACC, however, 
+it is possible and would likely be ideal to align the method with OpenACC in the future. However, at least 
+currently the OpenMP specification is less descriptive and has less stringent rules around descriptor based
+types so does not require as complex a set of descriptor management rules (although, in certain cases 
+for the interim adopting OpenACC's rules where it makes sense could be useful).

I think it is better to focus on describing what is the implementation in OpenMP and move the comparison with OpenACC to the last paragraph under a separate heading.
