Should processors work with references? I would think that they should, 
but the following fails. (My backmatter page numbers need to be marked 
to distinguish them from bodymatter pages. I can automate applying a 
processor based on the location for index register entries, but not for 
references.)

    \defineprocessor[xx][style=slanted,after=n]
    \starttext
    \section[xxx]{Processor testing}
    Why cannot a processor be applied to a reference? \at[xx->xxx]
    \stoptext

Thank you, Wolfgang, for that. But it still does not handle the after 
key, as I had in my example, and which works in a processor for index 
entries. Is there no way to do this?

The processor mechanism has no after key and I have no idea what it is 
shoudl do.

My apologies, Wolfgang and list. The key I use is right, as in the 
following snippet from my environment. I should have checked my files 
instead of relying on memory when I replied.

When I add it to your solution it does work.

    \defineprocessor[Back][
                            style=slanted,
                            right=n,
                           ]
    \defineprocessor[notBack][
                               style=normal,
                              ]

    \defineregister[Index]
    \setupregister [Index][n=2,
                            command=\Word,
                            balance=no,
                            compress=yes,
                           ]

    \starttexdefinition unexpanded index
       \dosingleempty\dostartindex
    \stoptexdefinition
    \starttexdefinition dostartindex [#sortkey]
       \doifmodeelse{*backpart}
          {\Index[Back->#sortkey]}
          {\Index[notBack->#sortkey]}
    \stoptexdefinition
    \starttexdefinition unexpanded seeindex
       \seeIndex
    \stoptexdefinition


    \starttexdefinition doIndex #INDEXTERM
       \expanded{\index{#INDEXTERM}}
    \stoptexdefinition

With this, I can use \index[Macintyre]{McIntyre, John} in the main text 
or an endnote and the indexing will identify the section. My simple use 
of the processor did not work, however, for references.

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.

Disable the page number (\setuppagenumbering[location=none]) and use 
\setupfootertexts to place it.

\setupfootertexts[margin][][{\convertedcounter[userpage][numberconversionset=number]}][{\convertedcounter[userpage][numberconversionset=number]}][]
\setuppagenumbering [alternative=doublesided,location=none]
