Hello,

I'm working an a application where many schema will be submitted so I need to validate them. And I'd like add some extra validations on the initial draft 7 schema.
For example :
I would like that :

• the "$schema" field to be mandatory.
• every property simple property (not type object) had an examples field
• every property property had a description field
• every "Datetime$" property be a { "type" : "string" , "format" : "date-time"}

Can you give me any advice on how to achieve that?
Thank you !
