Validation
The value of this keyword MUST be an integer. This integer MUST be greater than, or equal to, 0.
An object instance is valid against "maxProperties" if its number of properties is less than, or equal to, the value of this keyword.
Graphical Representation
The constraint is represented in line within the diagram, properties with the icon 
apply to instance Object values.
Constraints are also shown in the property grid when the containing schema is selected.
If the schema is not allowed to contain an object the constraint is ignored, and not shown in the property grid.
The constraint values are also shown on the tooltips (select and hover over an item in the diagram).
Editing
Its value can be edited in the following ways
- In place on the schema object by expanding the properties and clicking on it once it is already selected.
- Edited via the properties window when the containing schema is selected
- Edited directly in the Json Source view.
It can be deleted by selecting it and pressing delete, or right clicking it an pressing delete.
