The document to be edited is separated into text and format components or segments and only the text segment is typically sent or transmitted to the remote device. After editing or review of the document text is complete, the text segment is returned to the network server, where it is recombined with the format segment to reconstruct a new document having edited text but formatting unchanged from the original document.
