AddedAttributeRequired
From HTML WG Wiki
Added Attribute: "required"
Issue: Justification for adding the "required" attribute, which "applies to all form controls except controls with the type hidden, image inputs, buttons (submit, move-up, etc.), and select and output elements. For disabled or readonly controls, the 'required' attribute has no effect." (Source: Web Forms 2.0, Section 2.7)
Details
Rationale: Why the "required" Attribute Should be Added
- Provides an explicit state binding, indicating that the user has to fill in a value in order to submit the form, rather than relying on font-characteristic changes or ascii art (such as: "Items marked with ** are required") which only implicitly mark the form field as "required" for those who can perceive the font change or process the ascii art.
