Overview

This class is abstract.

Subclass must implement #checker, and #label_provider

This class is an abstract base implementation of a _model validation factory_ that creates a validator instance and associates it with a fully configured DiagnosticProducer.

A validator is responsible for validating a model. There may be different versions of validation available for one and the same model; e.g. different semantics for different puppet versions, or different types of validation configuration depending on the context/type of validation that should be performed (static, vs. runtime, etc.).

This class is abstract and must be subclassed. The subclass must implement the methods #label_provider and #checker. It is also expected that the subclass will override the severity_producer and configure the issues that should be reported as errors (i.e. if they should be ignored, produce a warning, or a deprecation warning).
