The diagram http://www.w3.org/2001/04/roadmap/xml-charset.svg http://www.w3.org/2001/04/roadmap/xml-charset.n3 suggests that one can look for a "charset" parameter on any XML document in a MIME body part; i.e. that the semantics of parameters named "charset" is shared across all media types. I wondered whether that's the case, which earned me... "Action DC: Verify that parameter names are local to each MIME type." -- http://lists.w3.org/Archives/Public/www-tag/2002Jan/0235 Indeed... [[[ For example, the "charset" parameter is applicable to any subtype of "text", while the "boundary" parameter is required for any subtype of the "multipart" media type. There are NO globally-meaningful parameters that apply to all media types ]]] -- http://www.ietf.org/rfc/rfc2045.txt Perhaps it's cost-effective to change this; after all, it seems silly for somebody to define a media type with a parameter named "charset" that means something else. But as it is, the algorithm in the diagram relies on more than the specs guarantee. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
