Overview

A YearMonthDuration literal.

yearMonthDuration is a datatype ·derived· from xsd:duration by restricting its ·lexical representations· to instances of yearMonthDurationLexicalRep. The ·value space· of yearMonthDuration is therefore that of duration restricted to those whose ·seconds· property is 0. This results in a duration datatype which is totally ordered.
