From Linked Earth Wiki
Add [[has type::<Type>]] in the wiki text for this property to specify Property Range
"Has subobject" is a predefined property representing a container construct that allows to accumulate property-value assignments similar to that of a normal wiki page. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.
