Schema Compliance check in Mocks

There are many topics on this on the forum (see below list) so I feel it would be a great benefit, especially when writing many mocks, to have the option of making the mock service check the request (and even optionally the response) message for schema compliance and error accordingly.

The last url gives some code but it would be much better if this was built in as I don't want to further complicate my mock script and it also makes this inaccessible to someone new to the tool.
