Context Selection

Contexts are selected for display by a presentation group by comparing the axis and their descendant members appearing in the group to the axes and members appearing in the context xbrli:segment. All contexts are selected in every presentation group except:

  1. If a context segment has an axis with a member for which the axis does not have that member as a descendant in the presentation group does not appear in the base set, then the context will not be selected (it will be filtered out).
  2. If the presentation contains an axis that does not have its default member as a descendant, and the context segment has no member for that axis, then the context will not be selected.

A warning is issued if the presentation group has axes but lacks descendants that would allow any context to be selected (6.26.1).

Contexts cannot be filtered based on anything other than the contents of xbrli:segment.

The set of periods in a set of contexts are on its Built-in Period Axis, or simply "period axis"
