Supposedly because of my limited understanding of TeX's expansion mechanism I haven't been able to get things working with this code:

The most important hint: please build test files that will compile. Take out anything which isn't relevant to your problem. Knowledgeable people on this list are quite unlikely to wade through code snippets. This page http://www.minimalbeispiel.de/mini-en.html is somewhat biased towards LaTeX, but you should get the drift.

> The purpose of this: I'm trying to use mkIV's page and linenumbering facilities for a critical apparatus (in this case endnotes with page and line references). As I didn't succeed with Hans Hagen's recent suggestion (cf. http://www.mail-archive.com/ntg-context@ntg.nl/msg49695.html)

Again, please provide relevant information. "Didn't work" is not enough information - maybe the color of your mousepad isn't quite right, maybe you forgot a closing brace, who knows? 

Finally: is the format of your apparatus (endnotes) a requirement? You can try and search the mail archive for "linenotes" and have a look at strc-lnt.mkiv. This will build one (or more) apparatus at the bottom of the page; I'm not sure if those can be selected in endnotes.
