How can I specify "Context path" on Tomcat 8 inside META-INF/context.xml in java war file?

It is not possible to put a war inside the webapp directory and set the path attribute in META-INF/context.xml file at the same time. Tomcat 8 documentation, clearly says about this attribute:

This attribute must only be used when statically defining a Context in server.xml. In all other circumstances, the path will be inferred from the filenames used for either the .xml context file or the docBase.
