Handling XML Doctype defintions in xml templates

Description: When xml Doctype node is present in a xml template in the ballerina code, currently the compiler gives a parser error. Is this a valid scenario to have DocType node in an xml template. If it is a valid scenario, how are we going to model it in the implementation

Example code,

public function main() {
    xml _ = xml `<!DOCTYPE note [
            <!ELEMENT note (to,from,heading,body)>
            <!ELEMENT to (#PCDATA)>
            <!ELEMENT from (#PCDATA)>
            <!ELEMENT heading (#PCDATA)>
            <!ELEMENT body (#PCDATA)>
        ]>
        <note>
            <to>Tove</to>
            <from>Jani</from>
            <heading>Reminder</heading>
            <body>Don't forget me this weekend</body>
        </note>`;
}
