Best document this before we forget about it.
Is this a good description of the command's behavior?
All structure heads, regardless of level, get a location number in the
order in which they appear. Like so (see also MWE at bottom of this
e-mail):
\section{Alpha}
% location number: 1; type: section; section number: 1
\section{Beta}
% location number: 2; type: section; section number: 2
\subsection{Aap}
% location number: 3; type: subsection; subsection number: 1
\subsection{Noot}
% location number: 4; type: subsection; subsection number: 2
\section{Gamma}
% location number: 5; type: section; section number: 3
\namedstructureheadlocation{X} then returns the location number of the
current X, where X is the name of a structure level (e.g. 'chapter',
'section', etc.)
If you ask for e.g. \namedstructureheadlocation{chapter}, and you are
not in a chapter, then 0 is returned.
Anything missing?
a location number is some kind of unique internal reference, a pretty
old feature btw, dating from the early days of context, when complex
interactivity was added, but it comes in handy here
