The meta query siteinfo allows to retrieve a list of magic words with basic information about them (aliases) [1]. Is there any way to retrieve more information about them, especially how they are supposed to be used: which ones should be used with {{#...}}, which ones are image parameters, ...

That would help a lot to code an external parser for wikitext.

Thanks in advance

Nico
