The Angular-CLI Documentation does not seem contain a full reference to the schema of the angular.json, is there any place to find a more complete list of available options?
With a little digging I found the Schema Reference for the angular.json file inside the @Angular/cli github repo at
https://github.com/angular/angular-cli/wiki/angular-workspace (no longer working, see update below)
Some of the options inside the angular.json file reference schema files. The schema of schema.json files can be found at http://json-schema.org/.
The original link no longer works. The (archived) version of the angular.json schema is still available.
However, an updated description is accessible via the Angular Docs.
