Considering #1264 and /Role, I will make a modest pass at updating the Conformance section.
Added hyperlinks to datamodel.html and expanded conformance section.
Based on deployment experience and community discussion, I have
refined the brief section on "Conformance". I have also made a
change in tone, such that "we" is not the 4 founder companies.
More explicit mention of URL being used with all properties.
Ok I've made a pass through aiming to bring this up to date a bit. I hope there is nothing too surprising here but do please take a look. @rvguha @scor @mfhepp @shankarnat @tmarshbing @chaals @vholland
