items representing fields in Complex Data type should be define in one group

eg:

          "item": [
            {
              "linkId": "PR-name",
              "type": "group",
              "definition": "http://hl7.org/fhir/StructureDefinition/Patient#Patient.name",
              "item": [
                {
                  "linkId": "PR-name-text",
                  "definition": "http://hl7.org/fhir/StructureDefinition/Patient#Patient.name.given",
                  "type": "string",
                  "text": "First Name"
                },
                {
                  "linkId": "PR-name-family",
                  "definition": "http://hl7.org/fhir/StructureDefinition/datatypes#Patient.name.family",
                  "type": "string",
                  "text": "Family Name"
                }
              ]
            },
            ...
            ...
            ...
       ]
