Size for XMLType only 4000 Bytes???

Question

Hello,
it seems, that the XMLType can only store up to 4000 bytes of
data.
When I enter a document larger than 4000 bytes the end is
truncated and the "extract"-method doesn't work anymore.
I have to store sizes of about 30-50 Kilobytes.
So, is there a way to set the size of the XMLType?
Has anyone else this problem?
TIA
Alex

Hello,
First, I want to thank you for helping me.
So, I've tried to create my table without the schema and the pb is still the same.
The index I create is a context index.
I create my table with the following query:
create table artefact(numArt number, art XMLType)
xmltype column art XMLSCHEMA "http://www.oracle.com/artefact.xsd" element "exportList";
CREATE SEQUENCE numArt START WITH 1 INCREMENT BY 1 NOMAXVALUE NOCYCLE CACHE 2;
create index ind on artefact(art)
indextype is ctxsys.context;
My schema seems to be Ok because it is validate by XMLSpy and when I use "little" data, everything is OK.
Here is the way I register my schema:
begin
     dbms_xmlschema.deleteSchema('http://www.oracle.com/artefact.xsd',4);
end;
declare
doc varchar2(10000) := '
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb">
     <xsd:element name="exportList" type="TypeExportList"/>
     <xsd:complexType name = "TypeExportList">
          <xsd:sequence>
               <xsd:element name = "request" type="TypeRequest"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="TypeRequest">
          <xsd:sequence>
               <xsd:element name="artifact" type="TypeArtefact"/>
               <xsd:element name="target" type="TypeTarget"/>
               <xsd:element name="keyword" type="TypeKeyWord"/>
          </xsd:sequence>
          <xsd:attribute name = "targetTool" type="xsd:string" use="required"/>
          <xsd:attribute name = "targetVersion" type = "xsd:string" use="optional"/>
          <xsd:attribute name = "sourceTool" type = "xsd:string" use="optional"/>
          <xsd:attribute name = "cmpa" type = "xsd:string" use="required"/>
          <xsd:attribute name = "command" type = "xsd:string" use="required"/>
          <xsd:attribute name="readOnly" type = "xsd:string" use="required"/>
     </xsd:complexType>
     <xsd:complexType name="TypeArtefact">
          <xsd:sequence>
               <xsd:element name= "object" type = "TypeObject"/>
          </xsd:sequence>
               <xsd:attribute name = "projectName" type="xsd:string" use="required"/>
     </xsd:complexType>
     <xsd:complexType name="TypeObject">
               <xsd:attribute name = "objectName" type = "xsd:string" use="required"/>
               <xsd:attribute name = "objectType" type = "xsd:string" use="required"/>
     </xsd:complexType>
     <xsd:complexType name="TypeTarget">
               <xsd:attribute name = "targetIP" type="xsd:string" use="required"/>
     </xsd:complexType>
     <xsd:complexType name="TypeKeyWord">
               <xsd:attribute name = "word" xdb:SQLName="word" xdb:SQLType="CLOB"/>
     </xsd:complexType>
</xsd:schema>'
begin
dbms_xmlschema.registerSchema('http://www.oracle.com/artefact.xsd',doc);
end;
Then, I insert the value as a clob (because the XML docs makes more than 4000 characters).
And then I search it with the query:
select numArt from artefact a
where contains(a.art,'test inpath(exportList/request/keyword/@word)')>0;
And if the attribute word makes more than 4000 characters, the word test is not found...
