Is it possible using cfdocument to create a pdf file that can be read but not
modified?  (CFMX 7)

It would be nice if someone could explain how the permissions works in plain
English.  I haven't been able to make any sense of Adobe's docs.

There is a list of permissions that you can apply - does that mean if you
don't apply them they don't have that permission?  I tried using NO permissions
as below but that doesn't seem to do anything.

<cfheader name="Content-disposition" value="attachment;
filename=delcnt#strZIP#.pdf">
<cfdocument format="pdf" encryption="128-bit" permissions="">
