Hello,

There is a discrepancy between the GridFS spec and the MongoDB GridFS documentation.

In the MongoDB GridFS doc doc it says:

"Applications may create additional arbitrary fields."

In the GridFS Spec it says:

"Note: some older versions of GridFS implementations allowed applications to add arbitrary fields to the files collection document at the root level. New implementations of GridFS will not allow this, but must be prepared to handle existing files collection documents that might have additional fields."

I've been told in HELP-3290 that the MongoDB documentation is wrong and that it needs to be updated to follow the spec.
