	This is the XML Schema for the Servlet 2.4 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 J2EE
	namespace:

	http://java.sun.com/xml/ns/j2ee

	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/j2ee"
	      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	      xsi:schemaLocation="..."
	      version="2.4">
	      ...
	    </web-app>

	The instance documents may indicate the published version of
	the schema using the xsi:schemaLocation attribute for J2EE
	namespace with the following location:

	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd

	]]>
    </xsd:documentation>
  </xsd:annotation>

  <xsd:annotation>
    <xsd:documentation>

      The following conventions apply to all J2EE
      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.

      <xsd:documentation>

	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 concatinate the element contents.  The multiple occurance
	of the element distributable is redundant and the container
	treats that case exactly in the same way when there is only
	one distributable.
