You could, of course, open the xml file in Word in its raw format and limit the spell-check to the <p> elements. That can be done by setting the whole document's proofing to 'no-proofing', then using Find/Replace to allow proofing within the <p> elements, before saving the corrected file in its original format.

The problem, though, is that someone is going to have to decide on a case-by-case basis of what corrections, if any, to apply to anything Word considers a spelling error.
