I am a cross-over lurker on the TEI list in that I am a documentary editor who reads both SEDIT-L and TEI, rarely posting to the latter. At the Jefferson Papers Retirement Series, we've had a good deal of experience tagging a wide variety of historical documents--including accounts--in XML. We use an XML editor, XMetal. Our staff has been able to tag more of the complex kinds of formatting over the years as they've gotten more experience. When we encounter really difficult material, we include an image of the page with the underlying transcription (for search purposes). Depending on your expectations and plans for your project, I would endorse the idea of putting your data in XML for both print and possibly electronic publication.
