Tangentially at best.

We must find a better place.

And the main problem is not where to document this (its natural place
is where all the standard properties are described), the main problem
is how to index it so that people could easily find it.  Also, where
else to mention that property in the manual, in related context.  We
don't seem to have anything about generating code...
