40 * <p>
41 * This filter also remembers enabled extension namespaces
42 * and filters out any extension namespaces that doesn't belong
43 * to those. The net effect is that disabled customizations
44 * will never pass through this filter.
45 *
46 * <p>
47 * Note that we can't just filter out all foreign namespaces,
48 * as we need to use user-defined tags in documentations to generate javadoc.
49 *

51 * The class needs to know the list of extension binding namespaces
52 * that the RI recognizes.
53 * To add new URI, modify the isSupportedExtension method.
