Thank you for answering. I have had looked into this source before and
tried exactly the same approach you descrived but I am on TeXlive 2019
where this is defined differently:
\unexpanded\def\registerpagerange#1#2#3#4#5#6#7#8% #1:class
#2:processor content, content todo: -- configurable
{\pushcurrentregister{#1}%
\edef\p_pagenumber{\registerparameter\c!pagenumber}%
\ifx\p_pagenumber\v!no\else
\registerpageseparator
\global\setconstant\c_strc_registers_page_state\plusone
\dostarttagged\t!registerpagerange\empty
\dostarttagged\t!registerfrompage\empty
\withregisterpagecommand{#2}{#3}{#4}{#5}%
\dostoptagged
\registeronepagerangeseparator
\dostarttagged\t!registertopage\empty
\withregisterpagecommand{#2}{#6}{#7}{#8}%
\dostoptagged
\dostoptagged
\fi
\popcurrentregister}
and, most importantly, does not work with this approach:
\unexpanded\def\registerpagerange#1#2#3#4#5#6#7#8% #1:class
#2:processor content, content todo: -- configurable
{ \pushcurrentregister{#1}%
\edef\p_pagenumber{\registerparameter\c!pagenumber}%
\ifx\p_pagenumber\v!no\else
\registerpageseparator
\global\setconstant\c_strc_registers_page_state\plusone
\dostarttagged\t!registerpagerange\empty
\dostarttagged\t!registerfrompage\empty
\withregisterpagecommand{#2}{#3}{#4}{#5}%
\dostoptagged
\ifnum#3=\numexpr#6-1\relax
f.%
\else
\registeronepagerangeseparator
\dostarttagged\t!registertopage\empty
\withregisterpagecommand{#2}{#6}{#7}{#8}%
\fi
\dostoptagged
\dostoptagged
\fi
\popcurrentregister}
May it be that parameters have changed since then?
Best regards
