適用范圍：This part of EN 1546 defines the Tag values required and describes the Dictionary mechanisms necessary for their utilization in order to achieve interoperability between IEP Systems where Data Elements have different lengths and/or the ordering of Data Elements in commands and responses is different from that defined in EN 1546-3. The mechanisms are based on TLV (Tag-length-value) definitions of each Data Element. Tags and mechanisms are also defined for handling Discretionary Data elements additional to those defined in EN 1546-3. The TLV mechanisms used are in accordance with ASN.1. Examples of utilization of Dictionaries are described in an informative Annex.
