Huh. So there's no good, universal advise I'm willing to give, except that you'll probably get nasty surprises with_any_ kind of complex office documents (regardless of the format being odf, ooxml, rtf or what else), if you read & write them across a wider variety of versions & different software products.
Any chance of taking a leaf out of WordPerfect's book? It's perfectly possible (in theory, and in my experience in practice) to round-trip a document between WordPerfect 6.0 (which ran on Windows 3.1) and WordPerfect 8, WordPerfect 2000, and presumably the latest versions of WordPerfect as well. I would seriously expect to be able to create a document using the latest WordPerfect, save it, open and edit it in WordPerfect 6, and then retrieve it back into the latest version with no loss of any features that v6 didn't know about!
The WordPerfect format has an explicitly defined code layout, and the spec says that unrecognised features are to be ignored but preserved. Okay, in Reveal Codes you can see (and delete) "unrecognised code", but that's the user explicitly doing it, not stuff being lost because it's not recognised.
