The following text by Noah Mendelsohn (extracted from
http://lists.w3.org/Archives/Public/www-tag/2003May/0062.html)
seems highly relevant to the "REST, uniformity and semantics"
thread. Note in particular the final sentence. (The point would be
even stronger, IMHO, if it explicitly mentioned the issue of "safe SOAP"
over non-HTTP bindings....)
