	This is the XML Schema for the WildFly 14.0 web application deployment descriptor.
	The deployment descriptor must be named "WEB-INF/jboss-web.xml" in
	the WAR file.  All JBoss Web deployment descriptors must indicate
	the JBoss schema by using the Java EE namespace:

        http://www.jboss.com/xml/ns/javaee

	and by indicating the version of the schema using the version element as shown below:

        <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           version="14.0">

	       ...

        </jboss-web>

	Instance documents may indicate the published version of
	the schema using the xsi:schemaLocation attribute for the
	Java EE namespace with the following location:

	https://www.jboss.org/j2ee/schema/jboss-web_14_0.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.

                and element names as the corresponding annotation.
