Yes, but the strict dumb application of what ended up being written 
written is definitely not what they intended, because it brings no 
benefits. I think everyone agrees that if the application is very 
careful about not specifying a charset anywhere, it shouldn't be 
forcefully added to the content-type header.

Anyway:
- Did you read the "for text media types" portion ? I find it important.
- "communicated as part of the Content-Type header": ISO-8859-1 is the 
default for HTTP, so one could consider it is communicated even if it is 
not physically present in the Content-Type header.
