My note was misleading. We can calculate display-size on the fly, but :

1. The display-size must not be different from external size eventually. (unless size is absent or invalid.)
2. It's still redundant since a similar calculation is done in the renderer.
3. This calculation has no special difference from ignoring "required" if size > 1 and non-multiple.


Attached a patch with "size > 1". It can be replaced with on-the-fly calculating display-size, if required.
