Problem updating config-config.xml from 1_2 to 2

I'm having issues trying to configure JSF 2.

I get the following error when starting up my tomcat 7 server locally.

SEVERE: Exception sending context initialized event to listener instance of class com.sun.faces.config.ConfigureListener
com.sun.faces.config.ConfigurationException: CONFIGURATION FAILED! cvc-enumeration-valid: Value '2.0' is not facet-valid with respect to enumeration '[1.2]'. It must be a value from the enumeration.

The error happens when I replace the following in faces-config.xml:

<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

with:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">

You've JSF 1.2 libs instead of JSF 2.0 libs in the classpath. Remove/upgrade them.
