secret Widget/Textarea (password)
textarea Widget/Textarea
output Widget/Label (data pulled from source, not a property)
upload
range
trigger Widget/Button
submit Widget/Button
select Widget/Listbox
select1 Widget/Listbox
- choices (not really a wiget, provides semantics for select and select1)
- item (not really a wiget, provides semantics for select and select1)
- value (not really a wiget, provides semantics for select and select1)
label Widget/Label (is more like a property of the widget it is attached to)
help (not a widget, help information for a form)
hint (not a widget, help information for a widget)

NOTE: There does not appear to be an equivalent for Widget/Checkbox, although similar semantics can be expressed with Widget/Listbox
