That depends on the container format and therefore it's the
responsibility of the container (e.g. a HTTP header) to remove the
whitespace.

Note that AFAICT RFC 2045 section 5.1 (that's what you're referring to
AFAICT) defines the MIME type specification as done with the
Content-Type header for MIME messages without defining exactly how the
actual type relates to the container.

IMHO we should not pay attention to whitespace.
