This is a variation on Quantity: A measured amount (or an amount that can potentially be measured).
There SHALL be a code if there is a value and it SHALL be an expression of time.
If system is present,
it SHALL be UCUM.
Inherited description: ELEMENTQUALIFIED controls the format of exported XML.
The ELEMENTQUALIFIED specification should be based on the elementFormDefault attribute of the
schema that defines the type.
To maintain compatibility, ELEMENTQUALIFIED will default to 1 (true) for literal format export
and will default to 0 (false) for encoded or encoded12 format export.
These were the values always previously assumed for the elementFormDefault attribute.
NOTE: Direct use of XMLExport method does not support the ELEMENTQUALIFIED. The export must be
done using %XML.Writer or SOAP support.
parameter XMLNAME = Duration;
Inherited description: This parameter provides the default XMLNAME for the class. If it is
empty then the class name will be used to construct a default XML name.
The default XMLNAME is used as the top level tag
when exporting objects and the export context
did not provide an XML container name.
parameter XMLPROJECTION = ELEMENT;
parameter XMLSEQUENCE = 1;
Inherited description: If the XMLSEQUENCE = 1, then the order of the XML elements must match the
order of the class properties. This allows us to deal with XML where the
same field appears multiple times and is distinguished by the order.
parameter XMLTYPE = Duration;
Inherited description: This parameter provides the default XMLTYPE for the class. If it is
empty then the class name will be used to construct a default XML type.
The default XMLTYPE is used when naming and referencing this type
in a schema and the schema context did not provide an XML type name.
