      This is the XML Schema for the Servlet 4.0 deployment descriptor.
      The deployment descriptor must be named "META-INF/web-fragment.xml"
      in the web fragment's jar file.  All Servlet deployment descriptors
      must indicate the web application 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-fragment xmlns="http://xmlns.jcp.org/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="..."
      version="4.0">
      ...
      </web-fragment>
      
      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-fragment_4_0.xsd
      
      ]]>
    </xsd:documentation>
  </xsd:annotation>

  <xsd:annotation>
    <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.

  <xsd:element name="web-fragment"

    <xsd:annotation>
      <xsd:documentation>

        The web-fragment element is the root of the deployment
        descriptor for a web fragment.  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 occurence
        of the element distributable is redundant and the container
        treats that case exactly in the same way when there is only
        one distributable.
