Allow othername & lineage about geekodoc

Toms yesterday made me aware that DocBook also supports the <givenname/> element. I think we should try to remove <firstname/> in favor of <givenname/>, since the latter is globally more applicable than the Western-centric <firstname/> element.

Removing <firstname> will cause validation problems. I would like to avoid these. Therefor I try to keep it for the time being and add <givenname>, <lineage>, and <honorific> to GeekoDoc.

If we still operate under the assumption that people have GeekoDoc v1 and v2 installed side by side, I think this might be a compatibility break worth making -- people would explicitly update to the new schema and it would be expected that there may be a few minor issues like this. No?

[tomschr]

Good point. In that sense, a major release could introduce a compatibility break. The question is if it's worth.

After I've looked into the doc-sle repo, it isn't not that much: I've counted 16 files which contains firstname. So it seems manageable...

Let me think about it.

The major repo where the tag is relevant is going to be the SBP repo, I guess. But that largely uses plain DocBook because the documents there are incompatible for a number of reasons.

Effort is probably low, could add the other tags.
