Invalid result for empty xml tags with required fields in data.xmldata module

Steps to Reproduce

import ballerina/data.xmldata;
import ballerina/io;

type Root record {
    string Book;
};

public function main() {
    Root|error a = xmldata:parseAsType(xml `<root><Book></Book></root>`);
    io:println(a);
}

The above code sample gives {"Book":null} as the rsult, while the expected result should be an error since the Book field in the record is a required field.
