Well, it really wasn't *crystal* clear to me... It
might have been this passage:
"Applications claiming to support this function shall
permit the following unit decimal prefixes to be
prepended to any unit symbol marked with “*” in the
unit table cell above. Adding a unit prefix indicates
multiplication by the given prefix value."
which might suggest that the unit symbol is
multiplied. How about:
"Adding a unit prefix indicates multiplication of the
(scalar) unit by the given prefix value; for example
km indicates kilometres, and km2 or km^2 indicate
square kilometres."
