Breaking too. HTML parser doesn't ignore content inside CDATA section, although it's a XML document.

topolik / EditLayoutsAction.java

Authorization block refactoring

	/**
	It's mainly a mind shift - from ALLOW by default to DENY by default - so that it's OBVIOUS when user is allowed to run each action.

	This means we list all cases when user IS ALLOWED to perform an action, not the cases when user is denied.

	Some rules we might find useful:
	1, every action should have BORDERS => outside the borders is no permission checking for the action
	2, in every action we list the cases when user IS ALLOWED => no more {PrincipalException}s thrown in each check
	3, in the end we DENY the execution by throwing PrincipalException => default behavior of the checkPermission method is DENY
	4, render, processAction and serveResource must always call the checkPermission method(s)
