What makes you sure line ends have already been normalised? In 2.11 it refers to converting them to #xA before passing them to the application, and suggests that it can be implemented by normalising before parsing (but doesn't have to be). I take the line-end conversion in 3.3.3 as duplicating the requirement in 2.11. If you implement it by normalising before parsing, you won't have to do anything about it in attribute normalisation. Similarly, I think the entity expansion in 3.3.3 is duplication of 4.4. And finally, I suspect that the authors just forgot the possibility of non-#x20 whitespace (arising from character entity references) in the paragraph about trimming and compressing spaces. The simplest solution seems to me to leave normalisation as it is, and change the Names and Nmtokens productions (which are only used for tokenised attribute) to require #x20 rather than S. This would make "foo	bar" illegal as a tokenised attribute, and a good thing too. -- Richard -- Spam filter: to mail me from a .com/.net site, put my surname in the headers.
