 Package validator implements value validations for structs and individual fields based on tags.
 
 It has the following **unique** features:
 
--   Cross Field and Cross Struct validations by using validation tags or custom validators.  
+-   Cross Field and Cross Struct validations by using validation tags or custom validators.
 -   Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
--   Ability to dive into both map keys and values for validation  
+-   Ability to dive into both map keys and values for validation
 -   Handles type interface by determining it's underlying type prior to validation.
 -   Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
 -   Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
 -   Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError
 -   Customizable i18n aware error messages.
--   Default validator for the [gin](https://github.com/gin-gonic/gin) web framework; upgrading from v8 to v9 in gin see [here](https://github.com/go-playground/validator/tree/v9/_examples/gin-upgrading-overriding)
