Attach a MS Word document to a PDF that will be viewed on the web

Wow.

This could have a nightmare of consequences!

First, most browsers do not fully handle PDF files. They might render the content of the PDF in the browser, but not give the user full access to it, such as for accessibility, filling in forms, executing buttons, and other common tasks. In this situation, I doubt they'd be able to open the attached Word.

Second, users might have a PDF-viewer plug-in in the browser, which should then give them more functions, like opening an attached Word file. But you do not know what the user's browser set up is.

Third, depending upon the user's settings, the PDF might authomatically be downloaded to their computer and the user might newer see it displayed in the browser at all. Hopefully, they'll notice a download arrow or some other indicator that the file was downloaded, but most average computer users I've observed just think that nothing happened and never know about the download.

Fourth, the only solid way to make this work is to give the user detailed instructions:

1. Download the file to your computer.
2. Open it with Adobe Acrobat Reader or other version of Acrobat.

I'm not sure if all PDF-viewers (non-Adobe viewers, that is) will be able to handle the attached Word file.
