[M4IF Technotes] File Type Box Question & Registering ftyp

We are making MP4 files.  Seems like the right thing to do is have a file type box that looks like this for our MPEG-4 files:
  major-brand="divx" (actually the number that represents "divx")
  minor-version=1
  compatible-brands="isom","other1","other2",... (and other numbers)
Is this what people are doing when they add file creation tools?
Where does one register for an 'ftyp' to get the official number?
