  DTD for Neuro - a PCM data format for 1+ dimensional signals over
  an ALingA Manifold. It is serialized as an Ogg bit stream for transport.
  It can be interleaved into an ALingA bit stream.
  (see ALingA.dtd).

  This DTD pertains only to the header packets of Neuro. The Neuro data are
  in the encoding format specified by the header, packed at the specified
  number of frames per packet. The data packets go after the header packets.

  The Neuro start tag goes into header packet 0, which is the Ogg identity header.
  The FrameType start tag goes into header packet 1.

  If there are any Metas, these go into header packet 1.
  After these go the FrameType end tag, and the Neuro end tag.

  If there isn't any Metas, then the FrameType element
  is EMPTY. The Neuro end tag goes into header packet 1.

  Metas may be used to specify information about channels.

  At least one data frame follow in packets, at the specified framesPerPacket.
