you seem to be saying that version 1.1.1 is marking the reaction element
for deprecation but that the reaction element itself won't become
invalid until a 1.2 or 2.0 version is released? This doesn't seem to
match with completely removing all reference of and to reaction elements
in the 1.1.1 specification...maybe I'm missing something?
