      This is the XML Schema for the Servlet 2.5 deployment descriptor.
The deployment descriptor must be named "WEB-INF/web.xml" in the
web application's war file.  All Servlet deployment descriptors
must indicate the web application schema by using the Java EE
namespace:
http://java.sun.com/xml/ns/javaee
and by indicating the version of the schema by
using the version element as shown below:
    <web-app xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="..."
      version="2.5">
      ...
    </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://java.sun.com/xml/ns/javaee/web-app_2_5.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.

                The web-app element is the root of the deployment
                descriptor for a web application. Note that the
                sub-elements of this element can be in the arbitrary
                order. Because of that, the multiplicity of the elements
                of distributable, session-config, welcome-file-list,
                jsp-config, login-config, and
                locale-encoding-mapping-list was changed from "?" to "*"
                in this schema. However, the deployment descriptor
                instance file must not contain multiple elements of
                session-config, jsp-config, and login-config. When there
                are multiple elements of welcome-file-list or
                locale-encoding-mapping-list, the container must
                concatenate the element contents. The multiple occurrence
                of the element distributable is redundant and the
                container treats that case exactly in the same way when
                there is only one distributable.

                        The session-timeout element defines the default
                        session timeout interval for all sessions
                        created in this web application. The specified
                        timeout must be expressed in a whole number of
                        minutes. If the timeout is 0 or less, the
                        container ensures the default behaviour of
                        sessions is never to time out. If this element
                        is not specified, the container must set its
                        default timeout period.

                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. Used in: user-data-constraint
