Would you mind telling me what library (JSON Schema validator tool) that you 
will be adding into Oxygen? (I can understand if you do not wish to tell me.)

Hi Roger, Thank you very much for the feedback. We use a third-party library 
for JSON Schema validation and, unfortunately, it does not support the 
"$anchor" and "$dynamicAnchor" keywords. This is mentioned as a limitation in

Hi Roger,

Thank you very much for the feedback.

We use a third-party library for JSON Schema validation and, unfortunately, it 
does not support the "$anchor" and "$dynamicAnchor" keywords. This is mentioned 
as a limitation in our 
user-guide<https://www.oxygenxml.com/doc/versions/25.1/ug-editor/topics/json-validating-json-schema.html#json-validating-json-schema__section_n4d_llf_y5b>,
 but, indeed, the message displayed for "$anchor" is not accurate at all.
We plan to provide full support for JSON Schema Draft 2020-12 in the near 
future by using another library. I will let you know when this support is ready.

Regards,
Florin

When I add "$anchor" to my JSON Schema, the Oxygen editor gives this error 
message:



  The keyword "$anchor" is not part of

  JSON Schema Draft 2020-12 specification.

  Therefore, it is ignored by the validation engine.



But that's not true. See section 8.2.2 of the 2020-12 specification 
(https://json-schema.org/draft/2020-12/json-schema-core.html#section-8.2.2):



Using JSON Pointer fragments requires knowledge of the structure of the schema. 
When writing schema documents with the intention to provide re-usable schemas, 
it may be preferable to use a plain name fragment that is not tied to any 
particular structural location. This allows a subschema to be relocated without 
requiring JSON Pointer references to be updated.



The "$anchor" and "$dynamicAnchor" keywords are used to specify such fragments. 
They are identifier keywords that can only be used to create plain name 
fragments, rather than absolute URIs as seen with "$id"...
