Stix2-Validator does not support json schema (draft-7) feature of "if-then" construct

[santosh-java]

Since the schemas are written in draft-07 of JSON Schema, I had created a custom object in our STIX representation for which I had come up with the custom schema for validating.

Attached the schema and one of the sample JSON instance which is not getting validated correctly.

Schema: x_signal_schema_ifthen.txt
Test Json Input:
Invalid_EDR_Signal.txt

Validation Output:
{
"messages": {
"errors": [
"x-signal--f9d5de15-7a32-94bd-7e62-e418b754fe6f: id: 'x-signal--f9d5de15-7a32-94bd-7e62-e418b754fe6f' does not match the id format ([object-type]--[UUID])"
]
}
}

Expected Validation Output should also show that the required property "x_hash_id" is not present along with the above 'id' error.

Question: Does the Stix2-Validator framework support 'if-then' construct? If not could you please let me know how one can achieve the value based check and have specific properties as required.

Thanks and Regards,
