How to solve this HTML 5 validation error related to Facebook like button?

Here is the text from validation engine:

Line 3170, column 261: Element name fb:like-box cannot be represented as XML 1.0.

…rue" border_color="" stream="false" header="false" height="260" ></fb:like-box>

Here is the code on Line 3170:

<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script><fb:like-box href="http://www.facebook.com/fburlhere" width="250" show_faces="true" border_color="" stream="false" header="false" height="260" ></fb:like-box>

Just after this error, there is also another error which reads:

Element fb:like-box not allowed as child of element div in this context. (Suppressing further errors from this subtree.)

referring to the same line number.
