If you make selectors require normalization form NFC, you can normalize the elements when atomizing them in the first place. For certain things, you might need to store both normalized and "original" representations. If selectors require NFC internally, you can safely normalize during the initial processing. That's part of the point of recommending NFC in the first place. You might still store the original code point sequence for rendering purposes (although that should be for non-markup content).
