Thank you again, Wolfgang.
I notice that, while the _contents_ of the setup are removed, and using
the reset setup introduces nothing into the text, there is no error or
warning generated. (This is also the case, I learned, with an undefined
buffer.) I can see that this can be very useful in a number of situations.
Can \resetsetups reset more than one setup in a single execution? When I
try \resetsetups[setupA,setupB] it appears to reset neither. I only ask
because of the plural name. It does not appear to be a burden to use
multiple \resetsetups commands.
Are there equivalent commands to \resetsetups and \doifsetupelse for
buffers? I could find nothing obvious.
The following example shows what I mean by the above statements. My
examples are often clearer than my descriptions.
\starttext

\stopsetups
