Hello, xhtml.cat in the PER-xhtml-modularization-20100414 tarball http://www.w3.org/TR/2010/PER-xhtml-modularization-20100414/xhtml-modularization.tgz refers to xhtml-ruby-1.mod, but that file is not included in the tarball. The zip file seems to have the same issue.
Is the omission or the catalog file incorrect? Ville
