New HTML Attribute

Status

Creating a new HTML attribute could possibility rectify HTML5's failure of not providing native longdesc functionality and semantics.

Bug 10455 was filed on August 26, 2010 to create a new HTML attribute. Since then some discussion of introducing a new long description attribute has occurred.

Use Cases

No use cases have been articulated or presented that are not already satisfied or could be satisfied by longdesc.

No Examples in the Wild

No examples in the wild have been presented of a new long description attribute.

User Agents

No evidence exists that user agents would implement a new attribute or in a manner intended by its designers.

Lacks Educational Material

No evidence exists that substantial documentation or tutorials are in place and ready to educate developers for a new attribute.

In contrast a longdesc support base already exists in the form of authoring tools, tutorials, books etc. These longdesc support materials will live on.

Lacks Backwards Compatibility

A new attribute would be void of all backwards compatibility. It would not:
