Norm’s playing around with media types.\nThis one<\/a>\nis served with application\/xml<\/a>.<\/p>\n\n

Let’s have a look at what should<\/em> happen in a perfect world if\nXHTML is served with that media type.\nRFC 3023<\/a> says;<\/p>\n\n

\nAn XML document labeled as text\/xml or application\/xml might contain\nnamespace declarations, stylesheet-linking processing instructions\n(PIs), schema information, or other declarations that might be used\nto suggest how the document is to be processed. For example, a\ndocument might have the XHTML namespace and a reference to a CSS\nstylesheet. Such a document might be handled by applications that\nwould use this information to dispatch the document for appropriate\nprocessing.\n<\/blockquote>\n\n

What that means is that one cannot assume that namespace\ndispatching will occur, and therefore the semantics of application\/xml are\nambiguous; it is reasonable that the recipient see it as XHTML\/HTML, but also\nreasonable that they see it as “XML” (such as in the IE XML tree view).<\/p>\n\n

In the real world of course, reality can trump specification; concensus\n(in the form of running code) may very well be that namespace dispatching\nis assumed, and in that case at least the ambiguity vanishes. But then\nwe’ve lost the ability to send plain-old XML. For example if somebody asks\nme for a sample XML document, I’d like to be able to send them some XHTML\nwithout it being interpreted by the other end as XHTML, just XML. I think\nit would be great if application\/xml could be used for this purpose, but\nit’s not a huge deal; text\/plain would also be appropriate in many cases.<\/p>\n\n

So I set up a little test<\/a>.\nLet me know what you see and I’ll record it. It could be useful in the\nsoon-to-come revision to 3023, enabling us to be a bit more specific\nthan “might”.<\/p>","protected":false},"excerpt":{"rendered":"Norm’s playing around with media types.
