[xml] Question about 'union' types in xmlSchemas

[GUY Fabrice <fabrice guy gmail com>]

Hi,

I have this schema :
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
  <xsd:element name="ELEMENTS">
    <xsd:simpleType>
      <xsd:union>
        <xsd:simpleType>
          <xsd:restriction base="xsd:int">
            <xsd:minInclusive value="10"/>
            <xsd:maxInclusive value="20"/>
          </xsd:restriction>
        </xsd:simpleType>
        <xsd:simpleType>
          <xsd:restriction base="xsd:int">
            <xsd:minInclusive value="30"/>
            <xsd:maxInclusive value="40"/>
          </xsd:restriction>
        </xsd:simpleType>
      </xsd:union>
    </xsd:simpleType>
  </xsd:element>
</xsd:schema>

and this simple xml file :
<ELEMENTS>5</ELEMENTS>

This xml file validates using xmllint (with libxml  2.6.19) although 5
does not fall in the interval [10,20] neither [30,40].

But maybe the 'union' type is not yet fully implemented ?
