ORA-19112: error raised during evaluation: ... Invalid text

Question

Hi!
I'm using Oracle 10g version 10.2.0.2.0.
If I an element is defined in a XSD file as:
            <xs:element name="cEAN">
             <xs:annotation>
              <xs:documentation>GTIN</xs:documentation>
             </xs:annotation>
             <xs:simpleType>
              <xs:restriction base="xs:string">
               <xs:whiteSpace value="preserve"/>
               <xs:pattern value="[0-9]{0}|[0-9]{8}|[0-9]{12,14}"/>
              </xs:restriction>
             </xs:simpleType>
            </xs:element>And I have a XML with:
<cEAN/>And other with:
<cEAN>7891515928001</cEAN>And I use a select like this:
        SELECT vw.*
          FROM tb_Carga tmp,
          XMLTABLE(XMLNAMESPACES('http://www.portalfiscal.inf.br/nfe' AS "nfe"),
                   '/NFe/nfe:infNFe/nfe:det | /nfe:NFe/nfe:infNFe/nfe:det'
                   PASSING tmp.XMLArquivo
                   COLUMNS
                     cEANTrib  VARCHAR2(14)  PATH 'nfe:prod/nfe:cEANTrib') vwWhy the first XML returns ORA-19112: error raised during evaluation: oracle.xml.parser.v2.XMLParseException: Invalid text '' in element: 'cEAN'?
Is any thing wrong in the XSD?
Thanks,
Luciana

Tried to figure out the correct regular expression, I think I would now opt for
<xs:pattern value="?|[0-9]{8}|[0-9]{12,14}"/>? matches "nothing/empty", or
[0-9]{8} matches 8 digits, or
[0-9]{12,14} matches from 12 up to 14 digits
...or...
<xs:pattern value="([0-9]{1})?|[0-9]{8}|[0-9]{12,14}"/>[0-9]? matches 1 digit or "nothing/empty", or
[0-9]{8} matches 8 digits, or
[0-9]{12,14} matches from 12 up to 14 digits
