[REQ] Allow additional info to be set for literature referencing #53
Description
Describe the solution you'd like
Citations using CSL allow to optionally specify page ranges, chapters, ... for a citation.
See Cite-Items.
It should be possible to add this info after an ID is set, because this information is specific to an ID.
Possible syntax:
[&&my-id{ locator: "123"; label: "page"}, other-id]
The info is set using the same syntax as with attributes.
Describe alternatives you've considered
Alternative syntax using () instead of {}, or JSON instead of CSS-like...
Would be less consistent with other elements.
Additional context
position and near-note properties should be set automatically by Unimarkup.
For this, the citation IDs must probably be stored during rendering to validate if a citation has already been cited.
