Comment:
The informative note has contents that should be clearer in the normative
text. Namely, a regular expression with alternate branches (a|ab) will match
the string 'ab' in a more "greedy" way if compiled as the informative note
suggests. As-is, implementations that follow the normative text will be
incompatible with implementations that also take the informative note into
account for the <input value="ab" pattern="(a|ab)"> case.
