Improvement of "Patents" and term "no date"

Hi,
Working on a style I noticed that the Zotero field “Assignee” is not available in CSL. I used a workaround, but of course it’s not the most intuitive if there is an “Assignee” field right in front of you.
Is there a plan to include this on the CSL and Zotero side?

Apart from that, I often make the mistake of using the term “no-date” only to be reminded by the validator that the actual term is called “no date”. I always wondered how it was chosen that certain terms have a dash, e.g. “no-place”, and some don’t?
Is this something that we’d want to “fix”? Is that even possible given that there will be a bunch of styles already using it and then suddenly not be validating with a new version of CSL is released?

Additionally, should the Zotero field country of a patent be mapped to CSL’s jurisdiction which is defined as “Geographic scope of relevance (e.g. ‘US’ for a US patent …)”?

No special reason, just sloppyness. And yes, that should be harmonized in a future version. I think it should be possible to convert styles using the older term variant to the newer version. (IIRC, we’ve done similar things during the last update.)
