'century' in schema for datatypes

Reference - http://www.w3.org/TR/2000/CR-xmlschema-2-20001024/#schema

[1] <simpleType name="century" id="century">
[2]  <annotation>
[3]   <documentation xml:lang="en"
source="http://www.w3.org/TR/xmlschema-2/#century"/>
[4] </annotation>
[5] <restriction base="timePeriod">
[6]   <period value="P100Y" fixed="true" id="century.period"/>
[7] </restriction>
[8] </simpleType>

Line 6 of this simple type definition is inconsistent with prose: "century
is generated from timePeriod by fixing the value of the duration facet equal
to 'P100Y'"
http://www.w3.org/TR/2000/CR-xmlschema-2-20001024/#century

Proposed resolution,

Modify the surface syntax to -
<duration value="P100Y" fixed="true" id="century.duration"/>
