[Zope] ClassSecurityInfo().declareProtected()

Hello, Is it possible to protect a class method with multiple permissions? ClassSecurityInfo().declareProtected(['perm1','perm2'], 'method') doesn't seem to work and ClassSecurityInfo().declareProtected('perm1', 'method') ClassSecurityInfo().declareProtected('perm2', 'method') will default to perm2 - the last assertion. Do I need to create a new permission?
