In Section 5.3, it says "The dMFlags field described above is a 64 bit field that allows initiator nodes to identify up to 62 items of base information to request in a request message (the first and last flags being reserved)." 62 bits can be used to indicate up to 62 diagnostic Kinds, but dMFlags reserves all "0"s that means nothing is requested, and all "1"s that means everything is requested. But at the same time, the first and last bits cannot be used for other purposes.

It is the language problem and accepted.
