Class: Structures_Form_RuleInterface

In HTML_QuickForm, all form rules extend a base rule class. While this is technically possible for Structures_Form, it prevents any other class from being extended to create a rule class. For example, an XML validation rule may be needed. Instead of wrapping some other XML class, a Structures_Form rule can extend that class and maintain the same API without the need for lots of developer work.

The constructor for the rule should define all the needed arguments. It is not possible to define the constructor here because the number of arguments may vary depending on what the rule needs.

This interface defines method needed to validate values.

A note contributors: I welcome contributions from others but I will not include any classes in the package that are not accompanied by a complete set of PHPUnit2 unit tests. Also, I am a stickler for documentation. Please make sure that your contributions are fully documented. Docblocks are not enough. There must be inline documentation. Please see Structures/Form.php for an example of what I mean by fully documented. Plus as you can see the interface is very simple.
