      This is the common XML Schema for the Servlet 3.1 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="3.1"> 
      ...
      </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_3_1.xsd

      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.

        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

  <xsd:complexType name="transport-guaranteeType">
    <xsd:annotation>
      <xsd:documentation>

        The transport-guaranteeType specifies that the communication
        between client and server should be NONE, INTEGRAL, or
        CONFIDENTIAL. NONE means that the application does not
        require any transport guarantees. A value of INTEGRAL means
        that the application requires that the data sent between the
        client and server be sent in such a way that it can‘t be
        changed in transit. CONFIDENTIAL means that the application
        requires that the data be transmitted in a fashion that
        prevents other entities from observing the contents of the
        transmission. In most cases, the presence of the INTEGRAL or
        CONFIDENTIAL flag will indicate that the use of SSL is
        required.
