MIME media type name : Application

MIME subtype name : Vendor Tree - vnd.vsf

Required parameters : none

Optional parameters :
none

Encoding considerations :

Vsffiles are binary data and thus should be encoded for MIME mail
transmission.  The same guidelines that apply to application/octet-stream
apply to vsffiles.

Security considerations :

Vsffiles are container files and practically any computer-generated
file may be placed inside a vsffile. As a result the security implications 
of a vsffile are impossible to assess.

Interoperability considerations :

This file type is not recommended for normal use, since Content-Type
information for the files contained within the archive are not known.
Instead, multipart/mixed should be used and each file should have its
own content-type.
