Seeing the comments about incompatibility above, I wonder if docx would be a better format for such a "polyglot format CV". AFAIK docx is a ZIP, and in a ZIP file the header/directory is located at the end of the file, so technically the beginning of the file can be "garbage".

(Not tested)

Edit: rereading, I also did not mean to imply the boot loader = garbage :) More that bytes that comprise a boot loader would look like garbage to the ZIP format.
