[whatwg] For Japanese language users, Web Forms should have a way to active/deactive for IME

[Masayuki Nakano]

Hi, I'm a member of Mozilla Japan and hacker of Mozilla.

I think that Web Forms should have a way to active or deactive for IME.
The function is same as WinIE's ime-mode property.

It is different for inputmode attribute.
Because inputmode attribute is the filter of key input.
But my proposal function is not it.

On system developing in Japan, the IME state controling is often needed.

I think following spec.

The 'imestate' attribute.
The attribute have following values.
'auto'
  When the input element or textarea element get focus,
  UA should care the IME active state suitable
  for the input element or textarea.
  e.g., If the input element is password field, UA should be disable IME.
  otherwise, UA should not change the active state.
'active'
  When the input element or textarea element get focus,
  UA should activate IME.
'inactive'
  When the input element or textarea element get focus,
  UA should inactivate IME.
'enabled'
  When the input element or textarea element get focus,
  UA does not care the IME state.
'disabled'
  On the input element or textarea element, user cannot use IME.

If the imestate attribute is not existing,
UA should care as set to 'auto'.

thanks,
