Hi, The XHTML Basic 1.1 [1] and XHTML 1.1 [2] DTDs were recently published with a link to the "xhtml-datatypes-1.mod" module. This module is defined in http://www.w3.org/TR/Markup/xhtml-datatypes-1.mod but the link that appears in the DTDs targets the folder in which the DTD is defined, resulting in a broken link.
Extract from one of the DTD (same problem in both): == <!ENTITY % xhtml-datatypes.mod PUBLIC "-//W3C//ENTITIES XHTML Datatypes 1.0//EN" "xhtml-datatypes-1.mod" > == Corrected extract: == <!ENTITY % xhtml-datatypes.mod PUBLIC "-//W3C//ENTITIES XHTML Datatypes 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-datatypes-1.mod" > == Thanks, Francois.
