           Summary: transform-origin with just one argument 'top' or
                    'bottom' not well defined
           Product: CSS
           Version: unspecified

It is possible to just use one argument for transform-origin that is either
'top' or 'bottom'. But this is partly in conflict with the following wording: 

""
If only one value is specified, the second value is assumed to be ‘center’. If
one or two values are specified, the third value is assumed to be ‘0px’.

If at least one of the first two values is not a keyword, then the first value
represents the horizontal position (or offset) and the second represents the
vertical position (or offset). The third value always represents the Z position
(or offset).
""

This implies that 'transform-origin: top' Is as if 'top center' was specified.
Actually all browsers interact as if 'center top' was specified (which makes
more sense). Maybe the second paragraph could clarify it a bit more.
