CMML is an XML markup language and can therefore be authored in any text editor. An example file and instructions can be found here.

Use anxenc to author Annodex content on the command-line from a CMML and Ogg Theora or Ogg Vorbis file. Reference the media file in the stream tag of the CMML file. Then call the tool:

anxenc is part of the tools of libannodex.
