RE: can attribute in XML schema hold value and unit
have, for engineering values where the convention is that 4.0m and 4.00m
represent different concepts (packing value, tolerance and units into the same
string), used single attributes specifically to prevent people processing them
using the standard decimal->floating point implementations in XML mapping
tools. W3C Schema validiation in these cases was not important - the model was
specified using RelaxNG and a implemented custom data types in Java server
It's certainly possible to pack the value and the unit of
measure into one attribute and many XML vocabularies do this. However, it
makes life a bit more difficult for anyone processing the XML, so two
attributes might be better.
I am creating a xml schema where
I have to making a 'attribute' but can a attribute hold a value and
My example is FlowRate, let's
the value and unit could be 100 GPM.
Can I have just one attribute
for 100 and GPM both. Some times it might be 80
So can a attribute hold both or
do I need element here.
