SuperForm adopts the concept of forms, fields and fieldsets, making it easy to define fields containing bundled validations and attributes. Form fields will be truly object oriented; that will make your code more DRY, so you won't need to define the same validations and attributes over and over again. SuperForm also contains fields for mundane concepts (like email and phone) - but you can still use it to code specific fields for your application. Forms are flexible, and allow you to provide specific validations and attributes. Also, SuperForm aims to supply a handy form builder for these fields.
This is still a work in progress, an early prototype. No release has been made yet. I'm working towards the first release.
