*: ASP types use all upper-case letters and typically have postfix _REQ, _CNF or _IND; RRC and NAS protocol types are extracted from standards and therefore do not have a _Type postfix
**: Constant defined in a function
***: Local functions shall not to be used by other modules
****: Counter variables do not need to have a prefix but may single characters like I, K, L, M, N
*****: All component variables are gathered in one record
