  <InformativeText>
    <Summary>The CSC Measurement characteristic (CSC refers to
    Cycling Speed and Cadence) is a variable length structure
    containing a Flags field and, based on the contents of the
    Flags field, may contain one or more additional fields as shown
    in the tables below.</Summary>
