[xml] XMLSchema-Instance broken in 2.6.22 ?

[Julien Lamy <julien lamy ircad u-strasbg fr>]

Hi folks,
As the title indicates, XMLSchema-Instance seems to be broken in version 
2.6.22 of libxml2.

Consider the following person.xsd file :

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"; >
        <xsd:element name="person" type="typePerson" />

        <xsd:complexType name="typePerson">
        <xsd:sequence>
                <xsd:element name="name" type="xsd:string" />
        </xsd:sequence>
        </xsd:complexType>

</xsd:schema>

And a corresponding person.xml file :

<?xml version="1.0"?>
<person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:noNamespaceSchemaLocation="person.xsd">
        <name>Unknown</name>
</person>

When I create a schema validation context with the NULL value (so that 
it will look for the schema references in the document), the call to 
xmlSchemaValidateDoc fails with version 2.6.22 saying that:
person.xml:2: element person: Schemas validity error : Element 'person': 
No matching global declaration available for the validation root.

Using version 2.6.18, the same call works fine.

Pre-parsing the schema works fine in both versions.

Is this a bug, or am i doing something wrong ?
