/** Internal representation of an authorization resource (the entity to which access is being requested). Consists\r
* of a type and an identifier. The constructor takes the request URI from an HTTP request and checks it against\r
* patterns for the the different resource types. In DR R1, there are four resource types:\r
- * <ul>\r
* <li>the feeds collection resource, the target of POST requests to create a new feed and GET requests to list\r
* the existing feeds. This is the root resource for the DR provisioning system, and it has no explicit id.\r
* </li>\r
* <li>a subscription resource, the target of GET, PUT, and DELETE requests used to manage an existing subscription.\r
* Each subscription has a unique subscription ID.\r
* </li>\r
