This is not really apropos your question, but what the heck... you may also want to support XML-to-XML conversion via XSLT.
In a previous role I helped develop the HR-XML Staffiing Exchange Protocol, which, in part, provides a standard schema for resumes. I'm not sure what kind of support the protocol has in real life, but based on the HR-XML membership (Monster, HotJobs, DICE, as well as PeopleSoft, SAP, Oracle) I assume there will be some employers that will accept an uploaded resume in this schema.
Now, convincing your HR person/interviewer that you really don't need to send a resume as a .pdf or .htm (let alone .doc)... good luck with that!
