IMO most of the problem with XML, and the reason why I hate using XML but find JSX and HTML perfectly fine, is that every XML document needs to start with some bullshit like:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

or:

    <?xml version="1.0" standalone="no"?>
    <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
        "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

It's not only verbose and extremely ugly but also impossible to remember.
