Potable Shop restrictions on items so far: - only one resprocessing element is evaluated. duration: from ims qti 1.2.1 best practice: duration The duration element is used within the item, section and assessment elements to define the permitted duration for the enclosed activity. The duration is defined as the period between the activity's activation and completion. The ISO 8601 format is used: PnYnMnDTnHnMnS. in mchc_smimr_104.xml example: 0000:00:00T:01:00:00d in ...101.xml: pTH02 iso website: http://www.iso.org/iso/en/prods-services/popstds/datesandtime.html and http://www.w3.org/TR/NOTE-datetime from some page: specified in numbers of years [Y], months [M] or weeks [W], days [D], hours [H] and so on, introduced by a ?P?, for example: P6W2D -> not a date, but only a duration makes sense: -> I shall take the ISO 8601 Time of the day hh:mm:ss format for now
