license metadata for JATS ignored

[castedo]

According to https://pandoc.org/jats.html "It is recommended to use the license field ..." instead of the copyright field (key value) for metadata values for JATS. Either the documentation needs to be updated or there is the following bug of ignoring the license field (key value):

STEPS:
With with-copyright.md and with-license.md

diff with-license.md with-copyright.md 
2c2
< license:
---
> copyright:

pandoc with-license.md -s -t jats -o with-license.xml
pandoc with-copyright.md -s -t jats -o with-copyright.xml

diff with-license.xml with-copyright.xml 
15a16,21
> <permissions>
> <license license-type="open-access" xlink:href="https://creativecommons.org/licenses/by/4.0/">
> <license-p>This document is distributed under a Creative Commons
> Attribution 4.0 International license.</license-p>
> </license>
> </permissions>

RESULT:
with-license.xml is missing a <permissions> element completely

EXPECTED:
For with-license.xml and with-copyright.xml to be the same, as suggested by the documentation.

Pandoc version?
2.18

I suspect this is for @tarleb. You probably have a preference on whether the doc vs the code gets updated.

I see now that using only the license by itself without any copyright key results in this problem.
I can use license key, but I have to also add some values under the copyright key too.

Thanks. The <permissions> element is now always included. That should fix the issue.
