    // When writing files with a Meta that uses sequences, it may be easier to
    // use events.  This is because FieldValueWriteReady will fire for each field
    // in the record and will automatically take into account any sequence redirects.
    //
    // Whenever you set a field value when writing (either directly or via the
    // FieldValueWriteReady event), the writer will check for sequence redirects and
    // immediately invoke any sequence resulting from a redirection.
    // Any subsequent invokations of the FieldValueWriteReady event will take into
    // account the redirection and specify fields arising from the new sequence.
    // Accordingly the application does not need to monitor for redirections.  It
    // just sets the value of each field supplied by the FieldValueWriteReady event.
