If you make an exception for the specific XHTML DTD then why not for every DTD! The argument that text/xhtml for content negotiation is a shaky one because the problem of content negotiation is a well known problem for HTTP. Proposed solutions include RFC 2295. A better solution is to employ specific request/response headers e.g. Content-Type: text/xml Content-Document-Type: http://www.w3.org/html50.dtd or, Content-Type: text/xml; document-type=http://www.w3.org/html50.dtd; charset=us The problem with content-type proliferation is that lots of software depends on known content-types. For example, how can you programmatically tell if a MIME message body contains XML? Parse it and if it succeeds then TRUE? Its alot easier to add a new header recognized by new UAs than it is to modify legacy and currently working code. Jonathan Borden http://jabr.ne.mediaone.net xml-dev: A list for W3C XML Developers.
