Receiving ORA-00902 on Table Creation

Question

Hi All,
Here's the scoop @ 10.2.0.2 64 bit version:
CREATE TABLE T_IRAC_XML_FROM_MISO_NEW
ID_NBR NUMBER,
XML_DATA XMLTYPE
XMLTYPE COLUMN XML_DATA
XMLSCHEMA "http://markets.midwestiso.org/BATODARTDATA/DARTUDSIRACMarketInfoBATO.xsd"
ELEMENT "DARTUDSIRACMarketInfoBATO";
If I leave off the "XMLSCHEMA" option, it works, but obviously there's a reason why I needed this specified. The XMLSCHEMA is registered:
select owner, local, schema_url from all_xml_schemas;
EMS_MISO YES http://markets.midwestiso.org/BATODARTDATA/DARTUDSIRACMarketInfoBATO.xsd
I get a ORA-00902: invalid datatype error.
I've also put "SYS." in front of the XMLTYPE in the Create Table statement with no difference.
TIA,
Boothie...

I think the issue is the definition of
     <xsd:simpleType name="OverrideNumType">
          <xsd:restriction base="xsd:decimal">
               <xsd:fractionDigits value="2"/>
               <xsd:totalDigits value="100"/>
          </xsd:restriction>
     </xsd:simpleType>
After commenting out the "totalDigits" facit I was able to register the XML Schema and create the table... The default is this is mapped to Number which cannot handle 100 digits. If you really need 100 digits you'll have to come up with a different mapping
