A few questions on registers, and on processors used with registers:
Can processors be used on entries in \setregisterentry? My tests so
far have not been successful.
Can processors be used on one level of a two-level register
{\index{Name+Processor->quotation precis}? Again, no success with
attempts.
Can something other than page numbers be the indexed item?
I have a book with many quotations, each identified by a number
(generated by \definelabel). For an index of quotations, it would be
more useful to point to that quotation number than the page number.
Perhaps the last requirement would be served by building a list with
the quote number and quotation precis, suppressing the page numbers
with pagenumber=\gobbleoneargument. But placelist does not seem to
behave as one would hope. The example in the wiki for setuplist
(shown below) does not print the numbers (1., 2.) in the first
braced argument to writetolist.
\definelist[Reprints][criterium=all]
\starttext
\section{Sec 1}
\writetolist[Reprints]{1.}{List entry A}
\subsection{Subsec 1}
\writebetweenlist[Reprints]{\hrule}
\writetolist[Reprints]{2.}{List entry B}
\completelist[Reprints]
\stoptext
I would prefer a register solution to take advantage of similar
formatting (column support and such) provided there, since this will
appear with the book’s standard indices.
