Enable previous and next buttons for navigating among this activity’s children.
Sequencing Control ForwardOnly[clusters only, boolean:FALSE]
Restricts the user to only moving forward through the children of this activity. Previous requests and using the table of contents go backwards is prohibited.

Selection Controls[clusters only]

Content developers have the ability to define sequencing information that indicates when to select certain activities and limit the number of activities to be chosen.
Selection Timing[clusters only, Vocabulary:Never]
Indicates when selection should occur. • Never – Selection is never applied; all of the children of the activity are selected by default. • Once – Selection is applied before the first attempt on an activity. • On Each New Attempt – Selection is applied before each new attempt on an activity. The On Each New Attempt option and its associated behavior are not specified in this version of SCORM.

Indicates the Selection Count data (True or False) is meaningful for the activity.
Selection Count[clusters only, Non Negative Integer:0]
Indicates the number of child activities that must be selected from the set of child activities associated with the activity. If Selection Count is larger than the number of child activities, all child activities are selected. This value is unreliable unless Selection Count Status is True. If Selection Count Status is False, all child activities are selected.

Randomization Controls[clusters only]

Randomization Controls describe when and what actions the LMS will take to reorder the available children of encountered cluster activities, while performing the various sequencing behaviors.

Minimum Progress Measure[clusters and leafs, Real [0..1]
