Hi, Arno,

Since there is no such definition like "simple tracker" and "smart tracker" in industry, I prefer not to define these terms in PPSP WG.
For a requirement draft, we can just use the words - "MUST", "SHOULD", "MAY" etc to differentiate which are necessary (for basic inter-op) and which are preferred. The real-world implementation will choose the appropriate functional set based on their design, rather than follow our requirements/definition of "simple tracker" and "smart tracker".
How do you think.

BR,
Ning Zong

Hi all

looks fine, just one small remark: in PPSP.TP.REQ-6 the term "smart 
tracker" is introduced with any further explanation. I think we need
to make the requirements for simple trackers and for smart trackers
more explicit.

Regards,
      Arno
