DTD being ignored?

I set up a dtd but the xml parser seems to be ignored. I have fields that are set to be required and others that are set to be straight character data (CDATA). If I remove the required field the the parse should fail, but doesn't. Also, the parser is trying to parse the cdata fields. I know this because if I create the xml with <![CDATA[my data]]>, instead of relying on the dtd, the fields go through just fine. My DTD looks like this: <!DOCTYPE webSync [ <!ELEMENT webSync (transaction+)> <!ATTLIST webSync syncID CDATA #REQUIRED> <!ATTLIST webSync nbTrans CDATA> <!ELEMENT transaction (syncItem, tname, compID?, actionCD, data?, pk?)> <!ELEMENT syncItem (#CDATA)>

<!ELEMENT tnam     (#CDATA)>

<!ELEMENT compID (#CDATA)> <!ELEMENT actionCD (#CDATA)>

<!ELEMENT data     (#CDATA)>
<!ELEMENT pk       (#CDATA)>
