So, how would you like to see it done? I am not super-glued to this  
proposal, it just made sense to my (admittedly warped) mind to allow  
users to control positioning and text flow separately, especially  
since (block-level) positioning is already fairly complete, with  
position: absolute; and 'position: relative;' and their cousins.

My proposal would probably look like:

   p #wraparoundme { position:absolute; left:auto; top:auto: margin:0  
1em 1em 0; wrap:both; }

Not significantly different from your proposal, except that it uses  
'position', which I would hope any experienced CSS user would  
recognize. I do like very much your idea of having the parameters and  
parameter sets work exactly the same way as other CSS style types.

That is clearly a problem to be resolved. On screen (@media: screen),  
floats allow things to move around so they don't overlap. In hard  
copy, this is less of a problem, since the paper sizes, etc., can be  
known before the content is printed.

Some designs might want the elements overlapped (a slim possibility,  
and rather silly in my mind, but possible). Other than that, the  
'float' changes that you are proposing and the 'position' plus 'wrap'  
changes that I am proposing do need to allow users to specify that  
elements need to move aside to make room for other elements.

Maybe we could use 'position: float;' That would tell the rendering  
engine that the EXACT position of the element is not fixed, only  
suggested, and that it would have to move to make space for other  
'floated' elements.
