-  # These are used as part of the REST call to perform a copy
-  #
-  #   x-dura-meta-copy-source
-  #   x-dura-meta-copy-source-store
-  #
-  # These are used to provide details about a space.
-  # You could probably set them on a content item, but that would be a little odd:
-  #
-  #   x-dura-meta-space-count
-  #   x-dura-meta-space-created
-  #
-  # These are use used as part of the REST call to set space access control
-  # (the * is replaced by the user or group name)
-  #
-  #   x-dura-meta-acl-*
-  #   x-dura-meta-acl-group-*
-  #
-  # These are used for some internal DuraCloud data wrangling,
-  # I'd recommend that you not use them in your code:
-  #
-  #   x-dura-meta-content-mimetype
-  #   x-dura-meta-content-size
-  #   x-dura-meta-content-checksum
-  #   x-dura-meta-content-modified
-  #
-  # That's it for the exceptions.
-  #
-  # One other set I'll call out is the values which are captured by the DuraCloud SyncTool.
-  # These are added automatically by the SyncTool, so you may have an interest in reading
-  # or updating them. Either way, it's good to be aware of them so you don't accidentally
-  # step on the values being captured for you.
-  #
-  #   x-dura-meta-creator
-  #   x-dura-meta-content-file-created
-  #   x-dura-meta-content-file-modified
-  #   x-dura-meta-content-file-last-accessed
-  #   x-dura-meta-content-file-path
-  #
-  # A few other notes:
-  #
-  # Stick with US-ASCII characters for property names and values
-  # There is a 2 KB total size limit on all user-metadata (this includes the metadata
-  # we create for you and that you add yourself)
-  #
-  # Both of these restrictions are put in place by Amazon S3, so we don't have much say
-  # in the matter.
