Security considerations : 
These files are intended to be read by a proprietary client (the "Unsealer")
which makes the unencrypted content available in a very limited fashion 
to a user's system. As the data format is private and encrypted using 
well-known algorithms, it is unlikely that the data could be spoofed. 
The client is also designed to refuse to work with data that is corrupt 
or ill-formed. This data does not contain any executable material.

Interoperability considerations : 
This mime-type is valid for Windows systems only.

data type within the MIME/HTTP environment and does not specify any 
details about the content format or semantics, except to refer to 
the software and specifications provided by Sealed Media. Company
