I don't like the current situation with a lot of different toplevel namespaces. I looked around as far as I could and didn't find anything this could really fit it. Personally I think it would be sensible if such modules - not just yours, but those dealing with any type of file, esp those produced by office suites - were placed under a Document:: root namespace. That would make yours something like Document::Word::View. The current Spreadsheet:: modules would fit in there nicely too, as would the PDF:: stuff.
Makeshifts last the longest.
