Hi Reece,

Read the whole CSS thread, and my oppinion is this:

The CSS should be a different library, implemented *on top of* your library.
I suggest you leave the library as is (of course - name changes, etc. 
are ok ;)), and implement only enough to make it possible for CSS to be 
implemented on top of your lib. Or even better, don't implement anything 
more. When you want to add CSS, just create a lib on top of Output 
Formatters. Then, you'll see what needs to be changed on Output 
Formatters library.

As for what Dave Abrahams said (default formatting on a stream), this 
could indeed be a nice addition to Output Formatters.
And it's really easy to add as well. There won't be any CSS. Just that 
for every type of formatter(decorator) class (pairfmt, 
containerfrmt,etc.) you can have a default stored within the stream 
class. *That's all*.

When you need to use a formatter (decorator) object and it's not 
provided inline (at the time of read/write), just query the stream - if 
the stream has a default formatter, use that one. I think that is enough.

Best,
John
