Internet Explorer 6 provides a way to query on line whether a specific version of an application is supported by the browser you are running on, or not. Examples for applications you can ask about are: "XML" and "HTML". Versions are decimal numbers such as 1.0, 2.0, and 3.0. Here is the syntax of this utility: 
document.implementation.hasFeature(application name, version number);
For example:

document.implementation.hasFeature("DOM", "1.0");
and:

document.implementation.hasFeature("XML", "2.0");
Let's check the current browser you are running on: "DOM" 1.0? "HTML" 1.0? "XML" 1.0? "HTML 3.0?. As you can see, it turns out that, for some reason, Internet Explorer 6 does not report as supporting DOM 1.0 and HTML 3.0.
