// nsSMILTimeValueSpec class

// An individual element of a 'begin' or 'end' attribute, e.g. '5s', 'a.end'.
// This class handles the parsing of such specifications and performs the
// necessary event handling (for event, repeat, and accesskey specifications)
// and synchronisation (for syncbase specifications).
//
// For an overview of how this class is related to other SMIL time classes see
// the documentstation in nsSMILTimeValue.h
