Yes, Jim, I found it under "http://www.w3.org/Addressing/",
but you can probably pick it up from <a href="ftp://foo.example.com/rfc/">the RFC</a>. 
Note the <a class="warning" href="http://www.ics.uci.edu/pub/ietf/uri/historical.html#WARNING" target="_blank">warning</a>.
Also <foo bar>.
<a class="junk" href="http://google.com/search?q=&lt;html&gt;">Search for some entities</a>.
