The PGN standard goes over each field in detail.  I may have jumped the gun on
the compatibility claim.  I assumed acd was standard, since S.J.E. wrote the EPD
code in Crafty.  It appears that neither dep nor acd is in the standard.  It is
obvious from context that both acd and dep mean ply depth.  Here are the major
headings from the PGN standard:
16.2.5.1: Opcode "acn": analysis count: nodes
16.2.5.2: Opcode "acs": analysis count: seconds
16.2.5.3: Opcode "am": avoid move(s)
16.2.5.4: Opcode "bm": best move(s)
16.2.5.5: Opcode "c0": comment (primary, also "c1" though "c9")
16.2.5.6: Opcode "ce": centipawn evaluation
16.2.5.7: Opcode "dm": direct mate fullmove count
16.2.5.8: Opcode "draw_accept": accept a draw offer
16.2.5.9: Opcode "draw_claim": claim a draw
16.2.5.10: Opcode "draw_offer": offer a draw
16.2.5.11: Opcode "draw_reject": reject a draw offer
16.2.5.12: Opcode "eco": _Encyclopedia of Chess Openings_ opening code
16.2.5.13: Opcode "fmvn": fullmove number
16.2.5.14: Opcode "hmvc": halfmove clock
16.2.5.15: Opcode "id": position identification
16.2.5.16: Opcode "nic": _New In Chess_ opening code
16.2.5.17: Opcode "noop": no operation
16.2.5.18: Opcode "pm": predicted move
16.2.5.19: Opcode "pv": predicted variation
16.2.5.20: Opcode "rc": repetition count
16.2.5.21: Opcode "resign": game resignation
16.2.5.22: Opcode "sm": supplied move
16.2.5.23: Opcode "tcgs": telecommunication: game selector
