Is there any alternative to parse a 1.1 XML document?

Haven't get a change to go through the XML 1.1 spec yet, but the seems to be mainly on extending further Unicode support.

"XML 1.1 improves on some of the short comings of XML 1.0, notably recognizing end of line. There currently exists a misalignment between what XML and Unicode defines as end of line, this affects particularly IBM machines, as well as systems communicating with them .

XML 1.1 also adds 2 new important characters NEL and a line separator. NEL 0x85 is used to mark the end of line and for completeness 0x2028 is used to mark the separation of line, this is extremely helpful in normalizing linefeed in text which plagues XML 1.0."
