<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think part of our problem is that in RFC3986 "host" is part of authority and authority is part of higher-part which begins with "//".<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The "mailto" scheme stuffs everything into path so doesn't have and authority owing to dealing with multiple recipients (it is a complex scheme) .<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">If "acct" was using higher-part rather than path it would simplify our job trying to normalize the various sorts of inputs for discovery.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The "acct" scheme uses ":" userpart "@" host (It defines userpart rather than re using userinfo). While being unusual having host in a path, I am guessing it is just the ABNF, so is a different host from the one in higher-part.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I don't think the below works for generic URI without a higher-part so we would be better saying or "acct" ":" userpart "@" host.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">That leaves out the mailto uri but processing rules to generically pick that apart are a real challenge, and would need to be restricted to a single recipient with no headers etc so would need it's own section for that scheme specifically
if we want to support it.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">There is also a problem with differentiating <a href="http://foo.org">
foo.org</a>:8080 as that could be interpreted as a scheme or <a href="http://foo.org">
foo.org</a> with a path of 8080 so being explicit about what schemes without higher-part are supported may be a good idea. <o:p></o:p></p>
