Re: How to extend btx rendering?

[Henri Menke <henrimenke@gmail.com>]

Okay, I have partly found out myself.  One has to add the field `eprint`
and `archivePrefix` to `categories.article.optional` in the file
base/mkiv/publ-imp-aps.lua.

But I don't want to edit any system files, because this is not portable.
 Also I don't want to have a copy of this file in my project directory,
because this is just redundant.

How can I add the two fields `eprint` and `archivePrefix` to
`categories.article.optional` from the document level?

Cheers,
Henri

N.B.:  In my original post there was a typo.  It should read

\starttexdefinition unexpanded btx:aps:eprint

(It was btx:aps:eprints in the original post)
