    99 Attachment permissions are handled by `LegacyAttachmentPolicy`, and unlike the permissions discussed so far, the permissions provided by `LegacyAttachmentPolicy` are not directly granted. Rather, the ability to create, view and delete attachments is determined by the attachment's parent realm and permissions the user possesses for that realm.

    101 The attachment actions are determined by the following
    102 permissions in the ticket, wiki and milestone realms:
