1. A method in a source device of supplying an application programming interface (API) command to a destination device via a communications channel, the method comprising:

  • specifying the API command using first tags having semantics defined based on a generic API document type definition (DTD);

    compressing the first tags using selected compression codes to generate compressed data;

    synthesizing a synthetic DTD, identifying the selected compression codes, by specifying second tags having semantics defined by a generic code book DTD; and

    transmitting the compressed data and the second tags via the communications channel, enabling the destination device to synthesize the synthetic DTD based on the second tags and a stored copy of the generic code book DTD, for synthesis of the API command by decompressing the first tags and based on a stored copy of the generic API DTD.
