Oh, I am sorry, I missed a sentence between those two you quoted.
You have incorreclty used Restrict Formatting and Editing function in Office 2007 and successfully got away with it.
Your approach does not work in Office 2010, because they have added a menu (which was absent in 2007) called
Paragraph spacing and a sub-menu
Custom paragraph spacing which leads to
Set defaults tab of
Manage Styles window.
One can not easily edit Ribbon in Office 2007, but if one adds
Manage style button to a Quick Access toolbar of Office 2007, he/she can get the your 2010 hack in Office 2007.
If you really want, I can record your hack in Office 2007 and prove that your approach is somewhat erroneous. Btw, I do have experience and I do understand what you are trying to do.
As for solution, I have already mentioned it.
