IIUC, what you are saying is that you would like to define few atomic tags and a few composite tag. A composite tag is presumably a union of some of those atomic tags. You need an ability to selectively export of the items that fall under the composite tag.
Orgmode allows selective viewing (and exporting) of tagged documents. I think all you need is to define a query and export only the visible portion of the document. (I don't use tagging much but you can get useful information from the manual) It still it beats me how would you solve the problem of migrating existing word documents in to Orgmode. Looks like that is a much bigger problem right there than the lack of facility for elaborate hierarchical organization. Jambunathan K.
