#526: Add optional attribute to capgen/prebuild
- Two proposed solutions, one for capgen and prebuild; this issue is for capgen
- Reintroduce optional attribute for CCPP physics schemes
- Schemes test for presence of argument if variable is declared optional in metadata
- Scheme metadata must have optional if (any) host model uses active other than default (.true.)
- #529: Draft PR for use of optional attribute in capgen
#527: Add tests for optional attribute
#528: Fortran 2008 MPI interface for CCPP framework and CCPP (UFS) physics
- Incompatibility of MPI communicator type (integer for old MPI, MPI_Comm for MPI F08)
- Currently talking with CCPP users to check if we need to support both (can do via framework, rather ugly)
- If only MPI F08, then #523; if both, then #530
#519: Ready to merge (requires CCPP physics PR as well)
#525 (merged): Add new test for active attribute with array transformation (variable actions)
