I noticed a few typos:

* Double dot in 5.6: "this mechanism are referred to respectively as attribute value templates and text value templates.. "
* Missing sentence-ending dot in 12.4 (the last several bullets): "A format token w generates numbers written as lower-case words, for example in English, one two three four ..." (in previous bullet points there's a normal-script ending dot)
* Double dot in 22.4 (under Error Conditions): "if a map element has two children whose normalized key values are the same.."

Strange comment in H.1 code, not sure this was intentional? Esp. the second line seems odd, as it is impossible to follow that path:
