No, of course not.
But then, what should a mail filter do when it meets one?
Do whatever it does when there's no DMARC info.
From: Your Bank <dmarc-protected@bank.example>, " skip DMARC"

The MUA ate the spaces. Perhaps:
From: Your Bank <dmarc-protected@bank.example>, "_____________________________skip
DMARC" <he.he@spammer.example>
The signature fails, so it is treated as if there weren't any. The Bank's
