Attributes for favicon

[Rahul Chandran]

A general query about the attributes used for favicon.

<link href="../images/favicon.ico" rel="shortcut icon" type="image/x-icon" />

1.What does (x) stands for in type="image/x-icon" ?
2.Apart from type="image/x-icon", is there any other type value and does the type value is compulsory for XHTML strict ?

Thanks and Regards.
