+Summary: XmlValidatingReader fails to validate XHTML document (because of URL resolving bug ?)
+
+When attempting to validate an XHTML document (with a DTD) using
+XmlValidatingReader with Mono built from cvs, the following exception is
+thrown :
+
+System.Net.WebException: The remote server returned an error: (404) Not Found.

+
+Note, this bug also exists in .NET 1.0 and 1.1, but is apparently fixed in
+.NET 1.2/2.0.
+
+I attached a repro for this issue.

+I know this test also fails on .NET 1.1, I also mentioned that in my
+bug report.
+
+Dunno the exact reason either, but it appears that the url for one of
+the entities in the XHTML 1.1 DTD
+(http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd) is not resolved correctly.
+
+It is fixed in .NET 1.2/2.0, does this mean that this will also not be
+fixed in Mono until version 2.0 of Mono ?

+oops, sorry I missed that line.
+
+I found that xhtml-notations-1.mod is referenced from
+http://www.w3.org/TR/xhtml-modularization/DTD/xhtml-framework-1.mod ,
+which is placed on different directory. So it is BaseURI and entity
+related bug.
+
+However, to solve this problem, entity base uri handling has to be
+wholly rewritten.
