SYSMOAS — API query should have a bnf specification

The query is only described using abstract syntax. While most of the API REST commands are fairly straightforward, it is not the case for query. There needs to be a BNF production that specifies the concrete syntax for query, which is the string that would be passed in the body of the post command

*Query JSON schema already available *

Per the Systems Modeling API and Services 1.0 beta specification on the OMG site.
https://www.omg.org/spec/SystemsModelingAPI/1.0/Beta1/About-SystemsModelingAPI
The section "Normative Machine Readable Documents" includes the following:
REST/HTTP API Schemas (JSON Schema) JSON SystemsModelingAPI/20230201/Schemas.json ad/23-02-25

The direct link for the API JSON Schema is: https://www.omg.org/spec/SystemsModelingAPI/20230201/Schemas.json

Given this Query JSON schema, this issue is resolved (closed; no change) and not blocking any implementation.
