[xml] Whitespace handling with schema

[Mark Van Peteghem <Mark Van Peteghem telenet be>]

Hi,

I have an XML document with a schema defined in it. I try to make 
libxml2 apply whitespace normalization as specified in the schema, but 
it doesn't seem to work. Here is an example:

   <contact xmlns:xsd='http://www.w3.org/2001/XMLSchema-instance'>
       <xsd:element name='contact' type='ContactType'>
          <xsd:complexType name='ContactType'>
           <xsd:choice>
             <xsd:element name='customer' type='collString'/>
             <xsd:element name='comment' type='collString'/>
           </xsd:choice>
          </xsd:complexType>
         <xsd:simpleType name='collString'>
           <xsd:restriction base='xsd:string'>
             <xsd:whiteSpace value='collapse'/>
           </xsd:restriction>
          </xsd:simpleType>
        </xsd:element>
      <customer>Name  </customer>
     </contact>

The whitespace is preserved when I call xmlTextReaderConstValue(...), 
even though <xsd:whiteSpace value='collapse'/> is specified.

Do I need to do something more to make this work, or can my application 
ask whether the string can be collapsed?

PS: I did add a schema valid context created with a null pointer, like I 
read somewhere:
       xmlSchemaValidCtxtPtr validator = xmlSchemaNewValidCtxt(0);
       xmlSchemaSetValidErrors(validator, SchemaValidityErrorFunc, 
SchemaValidityErrorFunc, reader);
       int rv = xmlTextReaderSchemaValidateCtxt(reader, validator, 0);
and rv is 0.
