The context.xml file allows defining one and only one webapp instance (context). However, you can create an explicit second context named "xyz.xml" and place it in the TOMCAT_HOME/conf/Catalina/localhost directory. This will cause a second, independent instance of the webapp to be deployed under the "xyz" context (note that it's the FILENAME, not the value within this xml file that determines the context path!)
If you wanted a single webapp instance under multiple context paths, you'd need an alternative approach.
