Periodical with columns instead of pages

[Quintus]

Is your feature request related to a problem? Please describe.
I stumbled upon a scientific journal which does not use pages. Instead, it prints column numbers as I have sometimes seen it in printed encylopediae before. That is, on each page, there are two columns printed, and these columns each bear an incrementing number. I am at a total loss how I can describe such a journal in CSL-JSON. It appears that the page number variable only takes pages, but I need it to take columns instead.

The specific journal in question is a German journal called “Süddeutsche Juristen-Zeitung (SJZ)”, which has long ceased to exist. Its last volume is from 1950. The article I want to cite is from 1948.

The journal has been digitised. You can look at it here: https://www.digizeitschriften.de/id/345574966_0003

Describe the solution you'd like
I need an additional number variable column instead of page. Or a variable pagetype which tells the CSL processor that page does not actually contain pages, but uses other locators, like, specifically, column.

Describe alternatives you've considered
There exists a locator column, but this does not cover my need. If I use it, my CSL processor will first print the label for “page”, followed by the starting column number, then the label for the “column” locator, followed by the column number I want to cite. The result looks like “Ulmer, SJZ 1948, p. 439 (col. 440)” which is nonsense. It needs to be “Ulmer, SJZ 1948, col. 439 (440)“. I use a footnote-based citation style I have written myself.

Because there are no locators in the bibliography, there is also no way to have “columns” printed instead of “pp.” in the bibliography entry for the article.

That is, to be consice, the issue is with the labels being incorrect.
