I think that the specification belongs, not with the normalize-text feature, but with the LexicalHandler (since people may define other types of handlers that we cannot predict). > Possible solutions: > > - reject normalize-text true if a LexicalHandler has been registered, > and reject LexicalHandler registration if normalize-text has been set > to true > - make normalize-text have a logical interpretation by default, and > switch to lexical if a LexicalHandler has been registered > - make normalize-text always have a lexical interpretation > - have separate normalize-text-logical and normalize-text-lexical > events, with reject-behaviour for the first The DOM's text-normalisation feature does *not* normalise CDATA sections, but I think that SAX's should.
