Incorrect XML conversion for the record types with single \#content field

[Nuvindu]

Description

Consider this record type.

public type Data record {
    string \#content;
};

When trying to convert a record value from this type to an XML value, it only produces an incorrect value.

The output: this is a string
The expected output: <Data>this is a string</Data>

When using an additional attribute it will correctly prints the xml output.

public type Data record {
    string \#content;
    @xmldata:Attribute
    int number;
};

The output: <Data number="1">this is a string</Data>

Steps to Reproduce

Run the following code in a single Ballerina file.

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

public type Data record {
    string \#content;
};

public function main() returns error? {
    Data document = {
        \#content: "this is a string"
    };
    xml xmlDocument = check xmldata:toXml(document);
    io:println(xmlDocument);
}
