ORA-30931 (again) when inserting data in XMLType table

Question

Hi,
I've created a table by registrating an XML Schema in the database.
The schema is the following :
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" xdb:storeVarrayAsTable="true">
     <xsd:element name="Customer" type="customerType" xdb:defaultTable="CUSTOMER"/>
     <xsd:complexType name="customerType" xdb:maintainDOM="false">
          <xsd:sequence>
               <xsd:element name="NAME" type="xsd:string" xdb:SQLName="NAME" xdb:SQLType="VARCHAR2"/>
               <xsd:element name="EMAIL" type="xsd:string" xdb:SQLName="EMAIL" xdb:SQLType="VARCHAR2"/>
               <xsd:element name="ADDRESS" type="xsd:string" maxOccurs="unbounded" xdb:SQLName="ADDRESS" xdb:SQLCollType="ADDRESS_TYPE" xdb:SQLType="VARCHAR2" xdb:maintainOrder="false"/>
               <xsd:element name="PHONE" type="phoneType" xdb:SQLName="PHONE"/>
               <xsd:element name="DESCRIPTION" type="contentType"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:complexType name="contentType" xdb:SQLType="CLOB" xdb:maintainDOM="true">
          <xsd:sequence>
               <xsd:any processContents="skip" minOccurs="0" maxOccurs="unbounded"/>
          </xsd:sequence>
     </xsd:complexType>
     <xsd:simpleType name="phoneType">
          <xsd:restriction base="xsd:string">
               <xsd:pattern value="\\(\\d\{3\}\\)\\d\{3\}-\\d\{4\}"/>
          </xsd:restriction>
     </xsd:simpleType>
</xsd:schema>
Now when I try to do an insert in the table and use mixed case in the contents of the description tag I get an ORA-30931.
Anybody got a clue why?
Thanks for your help!

xsd:any does not allow text() nodes outside of elements, it only allows child elements. If you want to add text() nodes outside of child elements this is mixed text. To get this you want to add mixed="true" to the complexType definition
