Note that the Packed Encoding Rules of ASN.1 (PER) is even more compact than OER. > Who and how will decide whether to use Automatic Tags?

Automatic tagging is specified by the organization which created the ASN.1 module that you using in your application. It is an integral part of the application's ASN.1 specification, just as the types defined by it are.
