A bit of scope creep due to wanting to point out the obvious "RR and SER"
are the same observation on the table. The main body for SER covers the
fact as well though in a very technical way.

I thought pointing out that examples are on the Wiki would be useful as
well - not everyone would think to go there for additional information. No
like though - just a pointer to it or the Internet generally.

It is not obvious to me what <table tocentry="1"> means...I suspect 1=yes...
