Cut-and-paste from the code I use in all ebooks (they prefer XHTML but you gotta draw the line somewhere) so I know there's no validation-level problem:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
But the popup didn't say there's some specific problem. It just sulked that it expected "html" alone.
Further experimentation with random commercial sites pulled up from browser history suggests that maybe they just don't like Transitional, period. (What the ### business is it of theirs?) Here's another one in red from recent browser history:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
