I am requesting that a class (not quite sure what it's really called, so I'll go with that) be added to $wgGroupPermissions that allows users to edit or move fully protected pages without them being able to protect or unprotect such pages.

I've been looking through the codebase (namely Article.php, EditPage.php, and ProtectionForm.php), but I can't find a singular place where such options would be easily defined (of course, I am unsure of how all the functions work, so that might be why).

Basically, I'm thinking of adding in two classes: 'editprotected' and 'moveprotected', which allows a user to edit or move a fully protected page, respectively. Of course, I'm not quite sure how that would work with the existing sysop rights, would these two rights have to be added in, or do sysops get them via other means, like they do now? Also, would having editprotected allow them to edit system messages (it shouldn't)?
