Looking for information on the dim attribute of base-units XML tag

Description

Can you explain the purpose of the dim attribute of the <base-unit> tag of the ucum-essence.xml file? All of the other children or attributes of the <base-unit> tag easily line up with columns of Table 2 of the HTML documentation. Except for dim. Attrubute values look like abbreviations for the kind of quantity column (i.e., the <property> tag of the XML file), but if this is true I can't find anywhere in UCUM that these abbreviations are used. On a wild guess, I checked the "Kind of Property" table of LOINC, but they don't match up with the LOINC abbreviations either.

The dim attribute specifies the letter used in the standard notation for dimension.

  • L - length
  • T - time
  • M - mass

etc.

The standard notation, for example, says that force is in the dimension LT-2M
