This document serves a rationale document for various parts of the HTML5 specification. Over time this page will be a complete rationale document.
Other Pages
- Why no namespaces
- Why no script implements
- Why not reuse legend or another mini-header element.
- Rationale for a variety of elements
Specific Elements
Plaintext
the <plaintext> element is a obsolete precursor to the <pre> element.[1] It is is now in the HTML5 spec as a method of stopping all further html token parsing. It lacks an end tag and just emits the rest of the page as plain text. It throws a parse error upon reaching the end of the document as it is not considered a valid element (and it is missing an end-tag).
Image
<image> element is treated as an alternate (but invalid) name for <img>. This is because some sites (around 0.2%) make this mistake. It is already treated as an image by most major browsers.
Meter and Progress (are not the same thing)
<meter> is not just a special case of <progress>. The progress element allows for indeterminate values and results in a completely different UI than the meter element.
See Re: <progress> draft for details.
