      This is the common XML Schema for the Servlet 4.0 deployment descriptor.
      This file is in turn used by web.xml and web-fragment.xml
      web application's war file.  All Servlet deployment descriptors
      must indicate the web common schema by using the Java EE
      namespace:
      
      http://xmlns.jcp.org/xml/ns/javaee
      
      and by indicating the version of the schema by
      using the version element as shown below:
      
      <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="..."
      version="4.0">
      ...
      </web-app>
      
      The instance documents may indicate the published version of
      the schema using the xsi:schemaLocation attribute for Java EE
      namespace with the following location:
      
      http://xmlns.jcp.org/xml/ns/javaee/web-common_4_0.xsd

    <xsd:documentation>

      The following conventions apply to all Java EE
      deployment descriptor elements unless indicated otherwise.
      
      - In elements that specify a pathname to a file within the
      same JAR file, relative filenames (i.e., those not
      starting with "/") are considered relative to the root of
      the JAR file's namespace.  Absolute filenames (i.e., those
      starting with "/") also specify names in the root of the
      JAR file's namespace.  In general, relative names are
      preferred.  The exception is .war files where absolute
      names are preferred for consistency with the Servlet API.

        The dispatcher has five legal values: FORWARD, REQUEST,

        A value of FORWARD means the Filter will be applied under

        A value of REQUEST means the Filter will be applied under
        ordinary client calls to the path or servlet.
        A value of INCLUDE means the Filter will be applied under
        RequestDispatcher.include() calls.
        A value of ASYNC means the Filter will be applied under

        A value of ERROR means the Filter will be applied under the
        error page mechanism.
        
        The absence of any dispatcher elements in a filter-mapping
