Description:

XML 1.1 makes essentially four changes to XML 1.0:


It increases the number of characters
that may legally appear in Names. 
Adds several new characters that may
appear in text if they are encoded as
numeric character references (C0
controls except NUL). 
Removes several characters so that they
may not appear in text if they are not
encoded as numeric character references
(C1 controls). Adds as a line-end character.

XML Schema 1.0 normatively refers to XML Namespaces 1.0 for the definition of QName and XML Namespaces 1.0 normatively refers to XML 1.0 for the definition of Name and XML 1.0 has fewer Name characters than XML 1.1.

That means that by a strict interpretation of the Recommendations, it is impossible to write an XML Schema for a document that uses the "new" Name characters. And by extension, it is impossible for an XPath expression or a protocol document to use XML 1.1.
