Thinking about it more, I'm not sure "markup" is as useful as DOM is.
We should have tests which test our DOM->Markup serialization.  Maybe
all the editing tests want that.  But I think most tests just want to
test the DOM, which (as demonstrated by the html5lib tests) can be
sterilized in a shorter format and exposes slightly different (and I
think in most cases more relevant) information.
