   Re: [xml-dev] rss 0.91 with rdf extension

[ Lists Home | Date Index | Thread Index ]

Bill is right here. In the web environment, HTTP headers should be used 
to determine MIME etc with extentions just being a fallback mechanism. 
You can always get just the headers with an HTTP HEAD; no need to 
request the whole resource.
