@omrfrkazt can you give a little bit more information on why we need this? I know you are giving this as a suggestion, but not sure what are the pros/cons. Can you talk more on how you used it before?

Pros:
Instead of defining all requests or responses chained validate functions, it makes this part more specific. for example, when the 'required' tag is used, it can automatically validate that field or by writing custom tags for custom validations, the same validation function can be used in many places.

Cons:
Friends who will develop the application need to know what the tags mean. documentation is good but dependency is dependency.

the example in this looks good :
