scope:

This International Standard specifies a uniform representation of human sexes for the interchange of information. It is intended to reduce the time required to record and/or format the representation of sexes and transmit the corresponding data; improve clarity and accuracy of interchange; minimize the amount of human intervention required for communicating the representation of sexes; and reduce costs. This International Standard does not prescribe file sequences, storage media, programming languages, or other features of information processing to be used in its implementation.
