Hi Tom,

Can you give me a scenario where it would be important to know that
milliliter, ml, and ML are all equivalent?  I think that one way to
achieve this would be to create a milliliter simpleType, which
enumerates the different forms.  Then, the volume simpleType would be a
union of the milliliter simpleType plus all the other values.  At the
moment, however, I am happy just to have a simple list.  As for your
second comment, I do locale-specific qualification to a limited extent. 
For example, gallon (US) versus gallon (UK).

Thanks for the comments!  /Roger
