OK, just to be clear, your concerns regarding the CSSOM spec are that it
should either:

(1) explicitly define support for use of the bracket notation for property
accessors for properties whose name is a style property defined by
CSSStyleDeclaration

or

(2) explicitly exclude such support

Is this correct? Do you have a preference?

Regarding cssFloat vs float, are you suggesting that the spec should
explicitly exclude the use of float, or merely add an informative note
reminding the implementer/user that the correct name is cssFloat and not
float?
