Statement Template validation does not support keys that are IRIs

[kelvinqian00]

Description: Statement Templates with rules that reference keys that are IRIs will not properly validate Statements, as the validation library cannot extract values properly.

Example: The following Statement (generated by DATASIM):

{
        "actor": {
            "mbox": "mailto:bob@example.org",
            "name": "Bob Fakename"
        },
        "context": {
            "contextActivities": {
                "category": [
                    {
                        "id": "https://w3id.org/xapi/cmi5/v1.0"
                    }
                ]
            },
            "extensions": {
                "https://w3id.org/xapi/cmi5/context/extensions/launchmode": [
                    "Review",
                    "Normal",
                    "Browse"
                ],
                "https://w3id.org/xapi/cmi5/context/extensions/launchparameters": "UVzahSV5qzm5DI1IZbyFJ9g1OT2W7",
                "https://w3id.org/xapi/cmi5/context/extensions/launchurl": "8S6Z7rLwyOJ4pwBvq",
                "https://w3id.org/xapi/cmi5/context/extensions/moveon": [
                    "NotApplicable",
                    "CompletedOrPassed",
                    "Completed",
                    "CompletedAndPassed",
                    "Passed"
                ]
            },
            "registration": "f851859f-b0fe-4b36-9939-4276b96d302d"
        },
        "id": "8dfe2e4f-5644-4486-ba16-a3289a507593",
        "object": {
            "definition": {
                "type": "https://w3id.org/xapi/cmi5/activitytype/block"
            },
            "id": "https://example.org/block/1587280280"
        },
        "timestamp": "2019-11-18T13:05:34.279Z",
        "verb": {
            "id": "http://adlnet.gov/expapi/verbs/launched"
        }
    }

should conform to the following Statement Template:

{
            "id": "https://w3id.org/xapi/cmi5#launched",
            "type": "StatementTemplate",
            "prefLabel": {
                "en": "Launched"
            },
            "definition": {
                "en": "Launched some event"
            },
            "inScheme": "https://w3id.org/xapi/cmi5/v1.0",
            "verb": "http://adlnet.gov/expapi/verbs/launched",
            "rules": [
                {
                    "location": "$.result.score",
                    "presence": "excluded"
                },
                {
                    "location": "$.result.success",
                    "presence": "excluded"
                },
                {
                    "location": "$.result.completion",
                    "presence": "excluded"
                },
                {
                    "location": "$.context.contextActivities.category[*].id",
                    "none": ["https://w3id.org/xapi/cmi5/context/categories/moveon"]
                },
                {
                    "location": "$.context.extensions['https://w3id.org/xapi/cmi5/context/extensions/launchmode']",
                    "presence": "included",
                    "all": ["Normal", "Browse", "Review"]
                },
                {
                    "location": "$.context.extensions['https://w3id.org/xapi/cmi5/context/extensions/launchurl']",
                    "presence": "included",
                    "scopeNote": {"en": "Insert scope note here."}
                },
                {
                    "location": "$.context.extensions['https://w3id.org/xapi/cmi5/context/extensions/moveon']",
                    "presence": "included",
                    "all": ["Passed", "Completed", "CompletedAndPassed", "CompletedOrPassed", "NotApplicable"]
                },
                {
                    "location": "$.context.extensions['https://w3id.org/xapi/cmi5/context/extensions/launchparameters']",
                    "presence": "included"
                }
            ]
        }

but it will report errors stating that the rules involving $.context.extensions['...'] locations are not being followed.

Solution: Use a different JSONPath library, such as Pathetic (which appears to support IRI keys).
