15.7.6 of ODF 1.0

The last sentence is: "Removing the protection makes these
sections accessible to the user, but updating the links or the 
index will not preserve the changes."

I guess that "accessible" means that users can now edit 
the sections.  However, I do not understand the rest of 
this sentence.  What is meant by "the changes"?

Cheers,
