Similarly to Anchor's `constraint =` attribute, it can be used to ensure constraints for the given accounts. The constraint can use both regular and compressed accounts. The most common use-case for it is ensuring the equality of public keys across regular and compressed accounts for security checks. DNS example is updated to use it for ensuring that compressed `NameRecord` accounts can be modified only by original signers, with `constraint = record.owner == signer.key()`.
