Both of these references:
   http://www.w3schools.com/schema/schema_dtypes_date.asp
   http://books.xmlschemata.org/relaxng/ch19-77073.html
state that xsd:duration is to use the [-]P... format, as does the core
spec at:
   http://www.w3.org/TR/REC-xmlschema-2/#duration
It's in the first paragraph of section 3.2.6.1.
