I'm trying to add my custom namespace to <html> element in JSF .xhtml file (actually, this namespace is not mine, it's Facebook's):
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"
xmlns:fb="http://www.facebook.com/2008/fbml">
JSF/Mojarra gives me a warning:
Warning: This page calls for XML namespace http://www.facebook.com/2008/fbml
declared with prefix fb but no taglibrary exists for that namespace.
I can understand what it means, but how to solve the problem?

You can suppress the warning by adding the following lines in the web.xml file of your application:
..
<!-- Debug Output for Development -->
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Production</param-value>
</context-param>
...
