I'm trying to migrate my HTML to XHTML. Unfortunately, PSGML barfs on the required "xml:lang" attribute because of the colon. The HTML 4.0 spec seems to indicate that (for HTML) the colon, among other characters, should be considered a name constituent. Changing the syntax type of colon to "symbol constituent" in the PSGML parser's syntax table leads to reasonable behavior for my X?HTML documents, but I do not understand ISO 8879 or PSGML well enough to say whether this is really a correct solution. Nor can I say how to implement it given that (AFAIK) the "correct" syntax table would vary according to the SGML instance. This arose in XEmacs PSGML package 1.18, psgml-version 1.0.1. Thanks for your attention to this issue. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 _________________ _________________ _________________ _________________ What are those straight lines for?
