MW: No. Only the results in ISO 15926 and some of the draft data models that
chart the changes made in developing it. If you have specific questions, I can
attempt to answer them from memory. But in general I can confirm that some
particular practices we adopted, including 4D and extensionalism were very
helpful in gaining traction, and it is this, rather than any philosophical
argument, that is why I am a 4 Dimensionalist (with extensionalism). (03)
