+Spec Lite: Switch to Turn Off Schema Validation
+===============================================
+
+:problem: While an API is in EXPERIMENTAL status, the schemas may not
+          accurately reflect the content of requests and responses,
+          causing the client to error out.
+
+:solution: Introduce a new option controlled by an environment variable
+           that will turn off schema validation.
+
+:impacts: None
+
+:timeline: Q-1 milestone (week of 16 October 2017)
