RE: Style guide: tristatecheckbox

I question the concept of a partially checked checkbox.

Checkbox and radio buttons are meant to hold  just the 2 boolean values: yes
or no.

If one can have  a 3 state checkbox  (to correspond to Yes, No, Not sure),
then why not a 5 state checkbox (that corresponds with something like
Strongly agree, Agree, Not decided, Disagree, Strongly disagree)?

The below definition conflicts with itself. 
If the item is partially checked, space rotates through checked, unchecked
and then partially checked again. 
However, the first bullet says if it's not checked that space  checks it! 

Is the implementation supposed to have 2 different code paths for unchecked
checkboxes depending on whether it was originally partially checked?

*	Three State Check Box 

*	If not checked, space checks the check box 
*	If checked, space unchecks the check box 
*	If partially checked, space will rotate through checked, unchecked,
and partially checked states.
