DFDL can't stop parsing a file without throwing an error.

You can tell DFDL that if the flag has a specific value, then the rest of the body of the file is to be treated as a single BLOB.

You just have to make a choice.

You should reconsider any solution that requires you to ignore a file based on the contents of it.
