[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Units of Measure
Actually, the Newton is the SI unit of force; Pascals are used for
pressure. And I wouldn't include the prefix (k, m, µ, M, G, etc.) as
part of the unit, instead treating it simply as an implied exponent of
10 (e.g., 3 for kilo, 6 for Mega, -6 for micro). So we'd have
<Impact force="345" unit="N" exponent=3 />.
This makes it easier to normalize different values, and limits the
number of SI units of measure you have to accommodate in the schema as
enumerations. It would be up to the stylesheet or application to take
the exponent and apply the proper SI prefix to the unit of measure when
the value is displayed.

I do find it odd though that you think that the fact that your format
isn't XML merits a ":-)" For most people on this list (who I assume are
here for the XML and not just for the Haikus) it means that it is not
really even a format to be considered. Why use <xx> markup at all if you
are going to be so incompatible?

That is not XML. The result of that particular markup is that unless
someone has your software they can't even parse it, still less figure
out what it means, why on earth wouldn't you mark that up as
<Impact force="345" scale="KPa"/>
