I think we should be removing way more code than including for this PR to make sense. The test outputs haven't even changed. This should be a bug fix, not a refactor. The biggest problem with this generator is that it's not in sync with the metadata. And the reason this generator is out of sync is that we didn't have reflection, and manually keeping it in sync was too expensive and fragile. So what we want to do is let reflection handle the whole thing, and the whole generator will have only one or two functions that recursively iterate over everything to generate the metadata. 🥳

This means the XML outputs will change completely, as they now reflect everything in the metadata, which is what this generator was meant for. Our intention is not to recreate the broken version, but to recreate it with reflection. If we don't fix it, reflection would mean more code rather than less, as we now have to force reflection to recreate the errors we had without it (which is even harder than just keeping the original errors). And that's going to be extra code just to maintain it broken.

I think another issue here is that we should probably address the other issue first, where we should remove those small workarounds from reflection to make it reflect into different key names. Only canonical names should be used. All generators should have access to the same fields with the same names. Making this happen is basically just the finalization of the previous issue we already merged. And maybe the @meta field is required to make that happen, since ambiguity might arise. Only after establishing the canonical field names can we use them to generate XML. 😅

What happened to this PR? I thought it would become more active after #1153 🚀

I removed the commit before pulling, after merging #1153, and GitHub closed it. I shouldn't have used the develop branch.

This fixes the XML generator, which was out of sync with our metadata,
by replacing it with a reflection-based implementation. The XML output
structure changes completely, but contains equivalent information.
Reason: See the new code comment in codecov.yml.
This adds support for all five admonition types, with corresponding
tests, plus tests for type-based friend declarations and pointers to
members.
