Based on the conversations that were held in London about propigating
smime-types up. I would like to propose that we remove enveloped-x400
content and signed-x400 content EITs and replace it with x400-content
EITs and S/MIME types. This is a difference from the SMIME-types from
the message draft, but in retrospect I believe that knowing the content
is of more importance that trying to one of the potentially many
security services. This also eases the code in moving SMIME-types from
layer to layer.
