Description

$subject

Steps to Reproduce

import ballerina/io;

public function main() {
    xml res = xml `<!DOCTYPE html/> <html>
            <head>
                <title>Dynamic Table</title>
            </head>
            </html>`;
    io:println(res);
}

The above crashes at compilation

Compiling source
        hinduja/temp_test:0.1.0

Running executable

 <html>
            <head>
                <title>Dynamic Table</title>
            </head>
            </html>

ballerina: Oh no, something really went wrong. Bad. Sad.

We appreciate it if you can report the code that broke Ballerina in
https://github.com/ballerina-platform/ballerina-lang/issues with the
log you get below and your sample code.

We thank you for helping make us better.
