Hi, The link in RFC3315 is actually incorrect -- it should have been http://www.iana.org/assignments/enterprise-numbers, without the file extension, and there's an erratum about this. HTML was generally (I say "generally" because there may be exceptions Michelle would know about) reserved for files that needed to include links to registration forms, like MIME/Media Types (which will be converted to XML shortly) and URI Schemes. As Barry said, we do intend to keep that same short http://www.iana.org/assignments/example format working for every current page, even the newly-created ones. We also prefer to see that format used in documents, since we can't guarantee that the file extension used for the long version won't change. (This information will be appearing on the website in some form.) (BTW: I've never tried writing to ietf@xxxxxxxx from our ticketing system, so Barry, would you mind pushing this along if it never shows up there?)
