* An implementation of {@link javax.servlet.jsp.tagext.Tag} that allows its body through if some authorizations
* are granted to the request's principal.
* <p>
* Only works with permissions that are subclasses of {@link org.springframework.security.acl.basic.BasicAclEntry}.
* <p>
* One or more comma separate integer permissions are specified via the <code>hasPermission</code> attribute.
* The tag will include its body if <b>any</b> of the integer permissions have been granted to the current
* <code>Authentication</code> (obtained from the <code>SecurityContextHolder</code>).
* <p>
* For this class to operate it must be able to access the application context via the
* <code>WebApplicationContextUtils</code> and locate an {@link AclManager}. Application contexts have no need to have
* more than one <code>AclManager</code> (as a provider-based implementation can be used so that it locates a provider
* that is authoritative for the given domain object instance), so the first <code>AclManager</code> located will be
* used.
