All, I also have just a few comments: 1.) I may be missing this, but there appears to be no element for quantity definitions. This seems like an important piece of information. I would recommend that we add such an element (and allow for multiple instances in different languages). 2.) The comment "<!-- REVISE -->" appears in the definition of the quantityType attribute. I don't know the exact meaning of this attribute. I think we should discuss: 1.) what it means, 2.) why it is required, and 3.) why there is a comment requesting a revision. 3.) In regard to Craig's comment below about degrees Rankine, I would like to note that I have seen both usages so both are used in practice. NIST publication 811 uses the term "degrees Rankine" in the conversion tables, but I don't know if 811 is an authoritative reference for non-SI units. (It is, of course, authoritative for SI units.) In any case it is important to note that in terms of the UnitsML schema the enumerated unit identifiers only have meaning in terms of their documented corresponding units. We have chosen terms which roughly match U.S. English usage for convenience; we could have named the identifier "XJ4234" and UnitsML would still work properly as long as this identifier was documented as referring to the Rankine temperature scale.

I, for one, am grateful for the opportunity to contribute asynchronously. I have no additions or changes to the posted content. I have one observation, and one question though. 1. Since I became involved with UnitsML, I've never really 'got' the QuantitySet element. I see that something called QuantitiesML would want to reference/incorporate UnitsML, but not the other way around. Perhaps I'm just being too much of a purist - certainly I can't imagine that having it in there being a barrier to implementation. 2. I've been under the impression for years that degrees in the Rankine scale are properly referred to simply as 'Rankine' and 'R' rather than 'degree Rankine' and '°R'. I have no evidence for this, and wondered if anyone on the list had an authoritative response?
