* Gecko/Firefox developers: Avoid using TYPE_OTHER. Especially for
* requests that are coming from webpages. Or requests in general which
* you expect that security checks will be done on.
* Always use a more specific type if one is available. And do not hesitate
* to add more types as appropriate.
* But if you are fairly sure that no one would care about your more specific
* type, then it's ok to use TYPE_OTHER.
*
* Extension developers: Whenever it is reasonable, use one of the existing
* content types. If none of the existing content types are right for
* something you are doing, file a bug in the Core/DOM component that
* includes a patch that adds your new content type to the end of the list of
* TYPE_* constants here. But, don't start using your new content type until
* your patch has been accepted, because it will be uncertain what exact
* value and name your new content type will have; in that interim period,
* use TYPE_OTHER. In your patch, document your new content type in the style
* of the existing ones. In the bug you file, provide a more detailed
* description of the new type of content you want Gecko to support, so that
* the existing implementations of nsIContentPolicy can be properly modified
* to deal with that new type of content.
*
* Implementations of nsIContentPolicy should treat this the same way they
* treat unknown types, because existing users of TYPE_OTHER may be converted
* to use new content types.
*
* Note that the TYPE_INTERNAL_* constants are never passed to content
* policy implementations. They are mapped to other TYPE_* constants, and
* are only intended for internal usage inside Gecko.
