What Part of Adsense Code Can You Change?

According to Google Adsense TOS you are not allowed to change any part of the code. After a bit of looking about there is a small part of code which you are allowed to change.

For example with my blogger layout it does not allow me to put in scripts into the page and leave in the <> tags, this is of course a problem. But you can change the <> tags for the XML equivalent which Google allows because you haven't changed to code, just the way it is formatted before being rendered in your browser.

What you need to do is change all the < with & l t ; and the > with & g t ; (With out the spaces) This will hopefully solve the problem.
