Info.rkt and multiple (custom?) licenses

I'm working on a very simple emoji lookup utility in Racket, and it looks like I'm going to include's emoji-test.txt, which has its own license, distinct from the license of my code. I have two questions:

  1. How to specify additional licenses in info.rkt? Or should I only specify the "main" license of the package, and mention auxiliary licenses elsewhere?
  2. How to specify a license not included in the SPDX License List? The list contains Unicode License Agreement - Data Files and Software (2016) license, but that seems to be different from the current one, which specifies 2022 instead of 2016... :confused:

  1. You can use AND in the SPDX format. See here for an example: r6rs/info.rkt at master · racket/r6rs · GitHub

  2. I think that Unicode license identifier is the right thing. The only thing that's changed is the copyright year.

Thanks. Going to use that format and include both licenses along with the package.
