I18N-ISSUE-251: Invalid content in longdesc [.prep-html-longdesc]

Section 3

"If a longdesc attribute has invalid content, user agents may make that content available to the user. This is because a common authoring error is to include the text of a description, instead of the URL of a description, as the value of the attribute."

Allowing authors to include the text of a description rather than a URL can lead to significant issues for non-English text.

User agents SHOULD NOT make this information available. Authors SHOULD learn to do it right.

1. authors may persist in misusing the attribute to the point that someone issues an extension that allows user readable content in the longdesc attribute.

2. user readable content in attributes cannot be marked up for bidirectional text, language, or styling.  Nor is it easy to indicate whether such text is intended to be translated or not for machines or translators. It should therefore be avoided where possible. (It's a bad enough situation to still have things like alt and title lying around, let's not make it worse, especially with a feature that encourages long, rich text content.)
