Scope and field of application This Recommendation specifies a set of basic encoding rules that may be used to derive the specification of a transfer syntax for values of types defined using the notation specified in Recommendation X.208. These basic encoding rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred. These basic encoding rules are used at the time of communication (by the presentation service provider when required by a presentation context).
