I see from looking at the source code that prefixes are used
to localize references. There is also some sort of automatic
prefixing mechanism. Can someone explain this more as it is
not clear to me from documentation in the source code.

Indeed, I have for a long time used keys such as
\placefigure [here] [fig:Einstein] {caption} {\externalfigure [Einstein]}
and
\startchapter [reference=ch:Einstein,title=Einstein]
also
\placeformula [eqn:Einstein]
    \startformula E = mc^2 \stopformula
etc.
where the "prefix" is just a label uniquely identifying the tag,
thus avoiding multiple definitions.
(I also do this practice in LaTeX using \label{})
I was unaware that ConTeXt handled this explicitly.
