For example, a method for a positioning protocol for first and second devices may comprise, at the first device: creating a message for the protocol at the first device, where the message comprises a set of included parameters from a plurality of allowed parameters, encoding the message by embedding each of the included parameters in an encoded string, and transmitting the encoded message to the second device. Similarly, a method for such a positioning protocol may comprise, at a second device receiving a message for the protocol transmitted by the first device, where the message comprises the included parameters, with each included parameter embedded in an encoded string, and decoding the message by decoding a subset of the plurality of included parameters and omitting decoding of included parameters that are not in the subset. ## Claims ### Claim 1 A method of supporting location services using a positioning protocol between a first device and a second device, comprising: determining a set of included parameters from a plurality of allowed parameters for the positioning protocol between the first device and the second device;
