I'm typically against errata that make sweeping changes but I have to acknowledge that the purpose of errata is to fix mistakes. The original policy for the version number in the XML declaration was broken and extremely short sighted. This is a glaring mistake that should have been fixed a long time ago but was probably left to lie since no other versions of XML were in the works at the time.

Oh joy. Another erratum that rewrites history because the working
group changed its mind. Sorry. I don't accept such errata as
normative. The spec is clear an unambiguous. There is no plausible
argument that the original spec made a mistake. The people who wrote
the spec knew what they were writing and why they were writing it.
Now, retroactively, somebody's decided they were wrong, and they're
going to fix it.
Sorry. This can't be done in an erratum. XML 1.0 says what it says.
Parsers are designed around it. If you're going to change the BNF
grammar, then you've invented a new language. XML 1.0 plus errata is
no longer XML 1.0. It is provably true that
<?xml version="1.1"?><root />
is a well-formed XML 1.0 document.
