XML Schema built-in data type namespace URI.

[KAZUMI Saito <ksaito@jp.fujitsu.com>]

The built-in datatypes defined by XML Schema part2 has namespace URI
(see 3.1 Namespace considerations in XML Schema part2): 

   * http://www.w3.org/2000/10/XMLSchema-datatypes

To declear the element which has the built-in datatype, which is correct?


<xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema">
  <xsd:element name="comment" type="xsd:string"/>
  ...

or

<xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"
            xmlns:xsdatatype="http://www.w3.org/2000/10/XMLSchema-datatypes">
  <xsd:element name="comment" type="xsdatatype:string"/>
  ...
