 * I am producing a form plugin. Can anyone recommend a good and reliable library
   to validate the fields on the backend side?
   What are the roles required to validate
   each field?

 * There are a number of built-in sanitation functions in the resources that Jason
   linked to. Sanitation helps prevent malicious code from being entered.
 * Validation confirms data is fit for purpose and should be as stringent as possible
   without being overly constraining. Ideal validation would be unique to a particular
   field, so generic validation functions would be less than ideal. Each should 
   be developed for the specific field. There are however a number of generic approaches,
   but the specific constraints will vary by a field’s specific purpose.
