I tried to validate the following stix pattern:
[file:hashes.MD5 IN ('3dc0fcf6d5de198741dfba217dee2a9b','3dc0fcf6d5de198741dfba217dee2a9b')]

and received
attern failed to validate: FAIL: '(3dc0fcf6d5de198741dfba217dee2a9b,3dc0fcf6d5de198741dfba217dee2a9b)' is not a valid MD5 hash.

But each hash should be validated seperately.
