Deprecated and defunct markup

{many elements on this page are wrongly marked as deprecated, this page needs review}

The following XUL tags and attribute should be considered deprecated, if not defunct.

The list below may include a few elements which are actually in use, but at a deeper level in the code. Even some of the information on the tags below may be out of date, but is provided here for historical reference and to help anyone who comes across them in old code or documentation.

Elements

• <actions> (listed here by mistake or was it a container tag?) Typo for <action> --Neil 03 March 2011
• <autorepeatbutton> (action occurs repeatedly on mouse hover--used to construct other elements; used in <arrowscrollbox> and large drop-down menus) So, not deprecated? --Neil 03 March 2011
• <bulletinboard> (made to support left/top styles, but <stack> can now do as well)
• <gripper> (inside of <scrollbar><thumb>; not to be used by itself)
• <listboxbody> (internal use only; part of XBL for <listbox>)
