As I recall, the problem with XML 1.1 adoption was that XML 1.1 was
not fully backwards compatible with XML 1.0: there were XML 1.0
documents that were not valid XML 1.1. That being the case, people
just didn't see it worthwhile to have two incompatible parsers.

As for ZWJ/NJ - the original intent was for these to not make any
semantic difference. There is a UTC action to collect cases where they
are being used to make a clear semantic difference (eg XXX means "sea
gull" and XX<ZWNJ>X means "republican"), so any feedback on such cases
would be useful.
