Hi Carsten, > But can it be agreed, that it's not specified for historical troff?
Disagree. The venerable CSTR 54.
7.1. ... Request, macro, and string names share the same name
list.
7.4. Diversions. Processed output may be diverted into a macro for
purposes...
So it's not that diversions share request, macro, and string namespace,
but that one diverts into a macro.
Cheers, Ralph.
