Overview

Package params provides the protocol definition and encoding/decoding feature of M3UA Common Paratemeters and M3UA-specific parameters.

All the parameters are in the same type: *param.Param, which helps handle any kind of parameters in the same way.

Specification: https://tools.ietf.org/html/rfc4666#section-3.2
