--- Comment #1 from Liam R E Quin <liam@w3.org> 2011-11-14 17:07:23 UTC ---
One of the changes in XML 1.1 was the introduction of Unicode NEL into the S
production, so that whitespace is not in fact the same in XML 1.1; this was one
of the reasons cited by vendors for not adopting 1.1.

The other significant remaining differences between 1.1 and 1.05e are
(1) handling of the version declaration;
(2) C0 control characters allowed in 1.1 and not  in 1.0 (but must be escaped).
    (character zero is still not allowed, however)
(3) C1 control characters must be escaped (to try to detect character encoding
    problems)

The purpose of XML 1.0 5e was to bring the spec up to date with Unicode and to
fix an error related to the version declaration, so 5e did not affect
whitespace or C0/C1 control characters.

Hope this helps.
