Yes, text should flow around it, as with the left and right float  
values. unless something in the text clears the float. So, auto side  
margins wouldn't work.

With float:left, additional float:left's  would stack up against the  
side, and same with float:right's, so yes, do that. I would have them  
appear in document flow order. The total width of two or more things  
with float:center that fit within the containing block would be  
centered within that block, and additional items with float:center  
would wrap to be centered below them.

A second itemthat is float:center and clear:center (or clear:all)  
would also wrap down below it, similar to other values for float.

I agree with the examples James Elmore gives in his December 29, 2007  
post.

Only if the containing block has columns with a column gutter  
intersecting the centered float.

Why not?
