Hi, I would love to see more metadata included in output, either as microformats, rdfa or both. There is already an hresume microformat specification, albeit in draft at the moment (see http://microformats.org/wiki/hresume ), and to include these attributes in the xsl would be fairly easy, I think.
For an example, I have already implemented a microformats and rdfa combined approach on the footer of my website, http://chops.isa-geek.net/. If you do not use a metadata enabled browser, have a look at the code of the name & email address to see what it produces.
Thanks for your consideration of this idea, and please feel free to ask me any questions if I have not made myself clear enough.
