The sentence "User agents must accept a presentationUrl using the http
 or https schemes" sounds very normative to me, which looks strange in
 a note that is informative-only by definition.

I suggest to rewrite to:
```html
<p class="note">The <code>presentationUrl</code> should name a 
resource accessible
to the local or a remote user agent. This specification defines 
behavior for
<code>presentationUrl</code> using the <code>http</code> or 
<code>https</code>
schemes; behavior for other schemes is not defined by this 
specification.</p>
```

Note that user agents will de facto be required to support http and 
https schemes because algorithms will mandate behavior in such cases. 
As such, there should be no need to add an extra normative statement 
such as "user agents MUST support presentationUrl using the http or 
https schemes".

The "should" in "The presentationUrl should name a resource 
accessible" could also be read as normative but it does not apply to 
user agents, so less of a problem.
