[css-transforms] translation values without units

WebKit allows unit less length values for translation values. Means:

translate(20, 20);
translateX(20);
translateY(20);

are accepted by the CSS parser even if the parser is not in SVG attribute mode. The spec reflects that with <translation-value>.

This is not the case for Firefox, Blink (not even for -webkit-transform) or IE. We probably should change the spec and replace <translation-value> with <length>. Opinions?
