Hello John,

Concerning floats, it means that there is only two direction for 
floats to go and two sides for floats to float too. This paring of 
left and right (with no top or bottom values) was mentioned in about 
three places before the most recent editors draft.

Floats either go downwards or upwards depending on there line-left or 

    downwards    |    upwards
  horizontal-tb  | horizontal-bt
   vertical-rl   |   vertical-lr

The pairs that go downwards are float:left/top and float:right/top. 
Here is one example.


The pairs that go upwards are float:left/bottom and 
float:right/bottom. Here are two examples.



Values for start and end would only be useful in dual layouts with ltr 
and rtl inline progression.

BTW, again I believe that MS has implemented this correctly.
