Suggested change

	Whenever a module references AVM modules that implement the telemetry parameter (e.g., a pattern module that uses AVM resource modules), the telemetry parameter value **must** be passed through to these modules. This is necessary to ensure a consumer can reliably enable & disable the telemetry feature for all used modules.
