> Security considerations: files are transmitted via secure channels (either

if the file contains sensitive information that should not be exposed
to eavesdroppers, you need to say this, and you also need to say something
about what the consequences of such exposure might be.

also, if presenting/using/evaluating the file on a user's computer presents
any security or privacy risks to the user (for instance, if it exposes
personal information or information from the user's disk files), you need 
to say this also.
