This is pretty good, but it would be better if this was a little more
specific. How about changing the first sentence to read:

 Cache manifests do not contain active or executable content and pose no
 immediate risk unless sensitive information is included within the

It would also be helpful, but not required, to include something about
how manifests containing sensitive material should be handled.

This is a pointer to the registration. It needs to be replaced either
with one to the specification as a whole or to the section(s) where
cache-manifest is specified.
