Copying a replication document
To customize a replication document for your particular use, you must often first make a copy of the document. This is because the metadata for some replication documents and their elements and attributes are now tagged as "read-only", based on their Access As identifiers. While you can create and update elements and attributes for these replication documents, you cannot modify or delete any metadata that is marked as "read-only". To be able to modify such metadata, you must first have a copy that is associated with your Access As identifier. When you create the copy, it is created with your Access As identifier, and you can modify any metadata that might otherwise be read-only.
Copying a replication document means that you want to create your own version of the entire replication document (including its elements and attributes), with a new name.
