How to write document for methods under static if?

[Yuxuan Shui via Digitalmars-d-learn]

Example:

/**
  test type
*/
struct A(bool T) {
        static if (T) {
                /// Case 1
                int ok(){ return 1; }
        } else {
                /// case 2
                int notok(){ return 1; }
        }
        /// Other
        int other() { return 0; }
}

///
unittest {
        A!true x;
        A!false y;
}

In documents generated by ddoc, only case 1 is included. In 
documents generated by ddox, none of the cases is included.

What's the proper way to write document in this case?
