Property:Is exclusive
From Wiki
The "is exclusive" property answers whether the subject of the page is inclusive. The value is a boolean. Usage example for a page:
{{#set:Is exclusive=false}}
Where the page subject is a design for decision purposes, this property tells whether the decision makers would normally be other than, or less than, all those affected by the decision. A modern legislature system tends to be exclusive, for instance, while an electoral system tends not.
See also Property:Is inclusive. A design may be both inclusive and exclusive when the two tendencies are roughly balanced, as for example in Blinap or practical democracy.
