+<P>\r
+The error filter allows you to redefine <I>on the fly</I> all the error messages\r
+flowing out of <B>Jigsaw</B>. The general principle is that all error messages\r
+comming out of <B>Jigsaw</B> are filtered, and intercepted. <B>Jigsaw</B>\r
+then uses internal requests to query some other resource for generating the\r
+exact text of the error message.\r

+The <A HREF="../api/w3c.jigsaw.filters.ErrorFilter.html">ErrorFilter</A>\r

+The ErrorFilter defines the following attributes:\r
+<UL>\r
+ <LI>\r
+ <A HREF="#base-url">base-url</A>\r
+ <LI>\r
+ <A HREF="#extension">extension</A>\r

+ <DD>\r
+ The base URL of the directory containing the error messages. When this filter\r
+ is enabled it will issue an internal request to the resource whose URL starts\r
+ with this base url attribute value, and whose name is the number of the error\r
+ code (plus an extra extension, see below).\r
+ <DT>\r

+ The extension of the resources that knows how to generate eror messages.\r
+ If the base-url attribute is set to <CODE>/errors</CODE>, and this attribute\r
