ASN.1's built-in simple types are shown in the following Table. The universal class number (tag) and a typical use of each type are also included. Table:Simple types in ASN.1, their universal tags, and uses. * indicates more than one tag. For a full list of Universal Tags, see th...
ASN.1 is flexible, allowing simple easily understood descriptions, yet has the power, for those who need it, to enforce complex constraints in which the type of information in one component of a message could be determined by the value of another component in the message. So ASN.1 is ...
