 Provide a function to handle pattern properties and set `supportPatternProperties` to take effect. The function takes the schema where `x-patternProperties` is defined on the root level. At this point `x-patternProperties` is changed to `patternProperties`. It must return the modified schema.
 
-If the handler is not provided, the default handler is used. If `additionalProperties` is set and is an object, the default handler sets it to false if the `additionaProperties` object has deep equality with a pattern object inside `patternProperties`. This is because we might want to define `additionalProperties` in OpenAPI spec file, but want to validate against a pattern. The pattern would turn out to be useless if `additionalProperties` of the same structure were allowed. Create you own handler to override this functionality.
