Hi Marco :)
placeholder attribute
Accessibility bug 545817.
From comment 6 of that bug: Text fields can have placeholder text that often visually appears as the italicized, or otherwise styled text inside the field. Users have learned that clicking the field removes the text.
Ideas:
- Make the placeholder text part of the accDescription. Jamie also suggested that if the name is otherwise unspecified (by means of a missing label), make it the accName instead, then.
- Alternatively, expose it as an object attribute.
Question: What if both title and placeholder are specified? The spec doesn't forbid that. If placeholder is exposed via accessibleDescription, it was suggested by Pete Brunet that title should be used and placeholder should be ignored in such cases.

output
- bug 558036
- Child nodes make up the content, the JavaScript property .value is there to deliver that content to JS programmers and doesn't need to be checked.
- The @for attribute points to other element(s) that contain, for example, the source of a calcuoation whose result is the actual content of this html:output element. Using CONTROLLED_BY and CONTROLLER_FOR relationsships is suggested and appears to make the most sense.
- support of STATE_INVALID?
