RE: [xml-dev] Comparable considered necessary

["Dare Obasanjo" <dareo@microsoft.com>]

XML namespaces is the only place I've seen URIs used significantly can you provide any others? Anyway, I decided to give one more shot at explaining my dislike of the whole URIs/URLs mess before bowing out. Here are some analogies 
 
URN: Microsoft  
URL: One Microsoft Way, Redmond, WA 98052 
URI:  Either of the above. 
Resource: The Microsoft Corporation
 
The above is an illustration of why I like URLs and like URNs but despise URIs.

	Dare, that quote means nothing to me. An identifier is just that and it's roles can be many, while I am interested in DNS based schemes. You have only used XML Names and XML Schemas for your arguments; their case is just a fragment of URI use and I'm only forced to use the first nowdays. I don't care about case sensitivity in XML Names; I do care about identifying resources, something that XML Names failed to do miserably (along with the mistake of using http URIs that are supposed to be addressable).
