JSon Scheme element definition Query

[PeteLong]

The following two elements ( system and doc_type ) are example elements defined in my JSon schema that was generated using Jsonix

How can these definitions be updated to specify min and max value effectively if this a mandatory element.

Also for numeric, how can i define the min and max values the element can have eg range of 4 to 10.

Are there examples of how to define constraints for elements.

Thank you for your help

Pete
