Browser page definition with permission: how to protect page following one or another permission

Hi,
I have actually a browser page protected by a permission (done in zcml definition).
I would like to protect my page following the user has at least one of two permissions.
How to do ?
Thanks in advance

Does not make much sense to me but feel free to perform additional arbitrary permission checks inside your browser view using plone.api.user.has_permission().
