Carol. re: "All of the other functionality works as expected, ie., bookmarks, hyperlinks interaction and so forth? "
In context of the usage of PDFMaker — Yes, if you have properly configured the PDFMaker for MS Word then the output PDF will have the Bookmark and hyperlink interactivity.
PDF Bookmarks (what is in the Bookmark pane of the Navigation panel) are not part of PDF page content.
"Copy-Paste", per se, of the Bookmark "tree" isn't possible.
The same applies for PDF Link annotations.
