-### $id ref Conclusion
+#### $id ref Conclusion
 
 We had a follow-up conversation with Nick Bollweg and Tony Fast about JSON schema and JSON-LD. In the course of the bi-weekly meeting, we discussed $id ref. From further review of how the [\$id property](https://json-schema.org/understanding-json-schema/structuring.html#the-id-property) works in JSON Schema we determined that the use for this flag is orthogonal to actual proposed usecase presented here. A future JEP may choose to pursue using this field for another use in the future, but we're going to keep it out of scope for this JEP.
