    /ATTRIBUTE=keyword(=value)

    This qualifier is used in combination with 3 possible
    keywords : BEFORE=date, SINCE=date or NONE. The last attribute
    change date is used in for selecting files. Use SINCE and BEFORE or
    NONE , but not both. The NONE keyword returns files which don't
    have a last attribute change date set. Examples :

    o  /ATTRIBUTE=BEFORE=date
    o  /ATTRIBUTE=(BEFORE=date,SINCE=anotherdate)
    o  /ATTRIBUTE=NONE
