+/**
+ * A container for all tag libraries that are defined "globally"
+ * for the web application.
+ *
+ * Tag Libraries can be defined globally in one of two ways:
+ *   1. Via <taglib> elements in web.xml:
+ *      the uri and location of the tag-library are specified in
+ *      the <taglib> element.
+ *   2. Via packaged jar files that contain .tld files
+ *      within the META-INF directory, or some subdirectory
+ *      of it. The taglib is 'global' if it has the <uri>
+ *      element defined.
+ *
+ * A mapping between the taglib URI and its associated TaglibraryInfoImpl
+ * is maintained in this container.
+ * Actually, that's what we'd like to do. However, because of the
+ * way the classes TagLibraryInfo and TagInfo have been defined,
+ * it is not currently possible to share an instance of TagLibraryInfo
+ * across page invocations. A bug has been submitted to the spec lead.
+ * In the mean time, all we do is save the 'location' where the
+ * TLD associated with a taglib URI can be found.
+ *
+ * When a JSP page has a taglib directive, the mappings in this container
+ * are first searched (see method getLocation()).
+ * If a mapping is found, then the location of the TLD is returned.
+ * If no mapping is found, then the uri specified
+ * in the taglib directive is to be interpreted as the location for
+ * the TLD of this tag library.
+ *
