Schema warnings for what seems to be a valid json schema

I have a json schema that I think is valid, but many warnings are surfaced in the editor.   I searched may web sites and tried to validate the schema several waya.  The schema seems to be valid.  I am actually able to use this schema to validate many input files - although I know that's not a definitive test….

Here is the schema - it's a bit long:
