Description
I'm looking at: https://github.com/opengeospatial/ogcapi-features/blob/master/cql2/standard/clause_6_basic_cql2.adoc
Few related concerns:
- This doesn't mention "IS NOT NULL" as allowed as an operator, but used in an example for IS NULL.
- I assume "NOT IS NULL" would also work, but this isn't mentioned.
- There's no example using just "IS NULL"
- Is there a CQL JSON Operator "isNotNull" also?

Research direction
Start with cql2/standard/clause_6_basic_cql2.adoc and review how IS NULL is described and used in its example. Verify whether IS NOT NULL, NOT IS NULL, and a JSON isNotNull operator are supported, then update the specification with the resolved syntax and representative examples.
