It looks like there is a type on the web page http://camel.apache.org/spring.html under the "Using camel namespace" section. It says:

Or you can refer to camel XSD in the XML declaration:

xmlns:camel="http://activemq.apache.org/camel/schema/spring"

When in fact it should say

xmlns:camel="http://camel.apache.org/schema/spring"
