Hi, Martin. Not surprisingly I've already hit several of the things you note, and not others.
Looks good. This is a slight typo: "An additional information that the unit attribute may be unnecessary when the unitRef attribute is present has been given (#1905)." It should be either "An additional warning" or just "Additional information".
Fixed.
Also, I'm confused by this: "The factor attribute has been added to the unit element, which shows factors of numerical values given in a referenced unit element." I thought the @formula attribute was the final decision? And its datatype is XPath, surely?
There is no @factor, so I deleted this entire bit. (I did not fix the bit that is in there about @formula, though ... hope to do that in a few.)
For the Japanese translations, I don't think I should be thanked; it's Kiyonori's team that's done the actual translation, and what I've been doing (which is nowhere near half-done) is largely mechanical. Good to thank Hanna, but perhaps put her after Kiyonori.
Did not touch this. I also commented out two items completely, as I consider them too minor to be in release notes (they are covered under the last bullet point for the Guidelines, "Corrections of typographic errors, improvements on explanations, and corrections of examples have been conducted in various sections of the Guidelines", which I'm not sure should be a bullet point, but perhaps a separate paragraph): * The description of schema validation of co-occurrence constraints has been cleaned up slightly (#1770). [Also, this was not true, we deleted said description. The section from which it was deleted needs some work, BTW.] * The change from http:// to https:// for relaxng.rng.
