[1226...@qq.com]

Hi all,

    Here are my requirement.There is a schema, eg:

   {

     "title":"sample",

     "type":"object",

     "properties":{

          "price":{

               "type":"integer",

                "minimum":"$priceRange"    //The minimum is not a fix number,but the data from priceRange in data instance.

            }

           "priceRange":{

               "type":"array"

            }

      }

    }

  In this framework,how can I make this function?  Thanks in advance!!
