It's not something you'd expect to see in a specification. It's a 
fundamental concept in the architecture of the Web. Media-dependent and 
platform-specific material has to be optional, since you can't expect to 
support every medium or platform (the platforms might not yet exist). On 
the other hand, content which is key to the application -- such as the 
logic behind a calculator -- clearly can't be optional.
