Wolfgang,

This is clearly a superior solution to my index-only attempt, handling 
all references to backmatter pages without regard to their being in the 
index or in text references.

However, the page number adjustment via \setupheadertexts is handled 
only at the top center (default location) of each page. Can you suggest 
how to modify this to support an un-processed page number in the right 
margin of the footer of backmatter pages? I currently use:

    \setupheadertexts[][chapter][part][]
    \setuppagenumbering [alternative=doublesided,location={footer,margin}]

and I do not see where 
{\convertedcounter[userpage][numberconversionset=number]} or something 
else to restore un-processed numbers might work, despite trying with 
\setupfootertexts, \setuppagenumbering, \setuppagenumbering, and related 
commands.
