        <Comment>Version 2.0 of the schema allows more information. Also, many additional units were added to fill in needs from other groups. Also added were unit symbols for RP66 units model for many of the units (using the SameUnit element).</Comment>

        <Comment>Changed the meaning of the Authority. They are: SI = Unit is defined in the SI system. POSC = unit added by, and defined by POSC. WITSML = additional unit declared by WITSML 1.2 as being needed.</Comment>

        <Comment>The usage of moles was off by a factor of 1000. The dictionary had consistently used mol(kg) as the the basic unit, rather than mole. The errors involved 25 customary units. All of these uoms are deprecated and replaced by correct uoms. the new uoms will consistently be like the old with the following replacement abbreviations: mol(g) to mol, mol(kg) to kmol, and mol(lbm) to lbmole. Also, the uom Grad (gigaradian) is deprecated, it being of little use, and being too easy to confuse with the angular measure, grad.</Comment>

    <Comment>This document is released as a more comprehensive dictionary of POSC units of measure. It includes the following additions. 1. More units to meet the needs of various groups. 2. Use of SameUnit element to record an RP66 equivalent symbol for the POSC unit. 3. an additional element, DimensionalClass, to give the dimensonality of the unit. 4. More extensive use of the QuantityType, although the listing given is not to be considered complete. The document is backward compatible with previous version 1.0, with the following exceptions: a) DocumentInformation has a slightly different form. b) all elements are in the same namespace.</Comment>
