 Dan, Tim,
 this is a relative outsider's view:

 Any string can be used to identify anything. Any URI is a 
string. But,

 on the other hand, HTTP has quite well-defined semantics working
with resources represented or updated by documents, and http:  
scheme URLs identify these resources, thus referring to the
document representations.

 Indeed, in XML Namespaces, URIs are used as strings, AFAICS the 
URI form is only so that ensuring uniqueness is much easier. 
Therefore I understand namespace names not as URIs but as strings 
with syntax equal to that of URIs.

 So while a car can be referred to by any string, using an HTTP 
URI for that is IMO mistaken.

 Best regards,
