That definition of user agent is not broad enough to encompass conformance

I know that "localized folder" seems weird there because "localized folder"
has not yet been defined when you get to that part of the document. I've
added "root of the".

The "locales/" is defined as the "container for localized content" (there
was a mistake in the definition). However, I would prefer not to change

Instead, I've tighten up the definition of both localized folder and the
container for localized content and added examples. Can you please check if
it is more clear now.

I made your suggested change to /en-au/.

The reason that the table is structured that way is that the optional types
are deemed to be more powerful then the required types: if the user agent
supports SVG, which could be an interactive animated icon, it will select
SVG first (rather then png or gif), and so on. PNG is also considered better
than GIF, so it is selected before gif.

I think CSS media queries might cover this. Currently investigating. Please
see the recent emails from Mark and Arve regarding this topic and please
raise your concerns there.

Added the example and rationale why the above does not work. Please check
that it is ok.

Media types are usually associated with content. Seems a bit strange to
define things in this way. Also, some engines might natively support, for
example, flash without requiring a plugin.

My proposal is that we drop the "plugin" attribute all together. Instead, if
the engine needs to defer to a plugin, then it should do so based on the
type identified by the content element.

<widget xmlns="http://www.w3.org/ns/widgets">

 <content src="maps.swf" type="application/x-shockwave-flash">
   <content src="maps.hml" />

I've also raised this issue earlier (wrt having different views of the same
content). This needs further discussion, but not here. Again, please respond
to Mark and Arve's recent thread on the matter.

Unicode characters have an inherent directionality so making ltr explicit
does not make sense here (i.e., Latin chars are always ltr, but if we made
lrt default, then Hebrew would go the wrong way!). ITS helps when you want
to mix languages and override the default behavior of the Unicode bidi
