DOCTYPE and URI

[Tom Otvos]

When specifying the URI for an external DTD in the DOCTYPE declaration, is
it generally accepted that a network-accessible document should be
specified, or a local one?  I often see examples where the URI is http://...
<http://...> , but I find it hard to imagine that *every time* a particular
XML file is parsed by a validating parser, the DTD is downloaded from some
remote web server.  The XML spec does not seem to talk about this, but is
there some search algorithm that allows a remote URI to be overridden by a
local file, if it exists?
 
Thanks, in advance, to anyone that can clear this up for me.
