schema validation for examples in swagger

Hello, 

With OAS 3.0 it's now possible to add several examples to requests and responses, to clarify the main use cases and how they would look like.

However, I noticed in the Swagger Editor (old or new), those examples are not validated against their schema or sub-schema.

May I suggest to add this as an improvement ?

This could avoid some typo errors while creating the examples based on the generic one.
