Meta security label not serialised

[Wpyh]

Describe the bug Meta of a fhir resource (e.g. MedicationAdministration) gets serialised for Response. However, I can see only some fields of Meta such as id, profile and source gets serialised whereas Security is missed out. This prevents putting a security label (https://hl7.org/fhir/valueset-security-labels.html) for the contained resource in the List API.

To Reproduce Issue 1: Steps to reproduce the behavior:

1. Create a Coding for Redacted security label (https://hl7.org/fhir/valueset-security-labels.html).
2. Set this to a Meta data as Security.
3. Set this Meta to a Domain Resource e.g. Medication Administration.
4. Set this Resource to a Reference
5. Set this Reference as an item of a ListResource
6. Serialise this ListResource using FhirContext.forR4().newJsonParser().encodeResourceToString()

Expected behavior Issue 1: contained.meta holds a security field with system and code Example

"resource": {
                "resourceType": "MedicationAdministration",
                "id": "someId",
                "meta": {
                    "security": [
                        {
                            "system": "http://terminology.hl7.org/CodeSystem/v3-ObservationValue",
                            "code": "REDACTED",
                                                          "display": "redacted"
                        }
                    ]
                }
            }
