In what case would 'Valid not detect an invalid representation?
For scalar X, X'Valid "yields True if and only if the object
denoted by X is normal and has a valid representation."

Certainly, if there is _no_ invalid representation of X, then
'Valid won't detect any. However, you should be able to use 'Size
to force the existence of an invalid representation for any
scalar, right?
