We will refactor the capability statements as follows: One capability statement for EHRs that is based on the U.S. Core EHR capability statement that adds support for asynchronous Task-based data requests & retrieval Servers SHALL support polling and SHOULD support subscription One capability statement for Payers that is not based on an U.S. Core capability statement and adds support for asynchronous Task-based data requests & retrieval Clients SHALL support polling and SHOULD support subscription A statement indicating that client systems SHALL either comply with the CDex asynchronous capability statement or comply with the U.S. Core capability statement (for at least one resource type) Will enforce expectations around authentication/authorization expectations either directly or by pointing to HRex (i.e. how server-to-server will work) Will also ensure that the capability statements render correctly in a manner similar to SDC.
