Please take a look at "Converting New URI Schemes or URN Sub-Schemes to HTTP"
http://dbooth.org/2006/urn2http/
Though not a formal proof, it represents an informal proof-by-construction that the capabilities of HTTP URIs are virtually a direct superset of those of URIs based on new URI schemes or URN sub-schemes.  The abstract:
[[
New URI schemes or URN sub-schemes are sometimes proposed for resource identification in applications where the HTTP protocol is deemed unsuitable.  This paper argues that URIs based on specialized HTTP URI prefixes would be a better choice in virtually all cases, even if the resource resolution or data transfer properties of HTTP are insufficient for these applications.   A simple recipe is presented for converting proposed URI schemes or URN sub-schemes to HTTP using specialized URI prefixes.  This technique cleanly separates the use of the URI as an identifier (to establish resource identity) from the use of the URI as a locator (to retrieve representations).  The resulting capabilities of the HTTP URIs are virtually a direct superset of those of URIs based on new URI schemes or URN sub-schemes.
