I think that Elliotte is referring here to the Saxon 6.5.x code base: I'm
not aware of any issues in Saxon 8.x where there are acknowledged bugs that
I have said I won't fix (unless there's a good reason, like I'm expecting
the spec to change).

Saxon 6.5.x includes a version of the AElfred parser, but I don't regard
that as part of the Saxon code base and I've declined to fix bugs there
because it's not my code and you have the option of using a different XML
parser: it was only included for convenience in the days before there was a
parser in the JVM.

As far as I'm aware the full list of non-conformances in Saxon 6.5.4 is
documented at:

http://saxon.sourceforge.net/saxon6.5.4/limitations.html

The reason these weren't fixed when I did the last maintenance release was
that they affected very few users, but fixing them would involve changing
substantial amounts of code which would almost certainly introduce more bugs
than they solved (some of them are also in areas where it's far from clear
what the correct behaviour is). There's no such thing as zero bugs,
unfortunately.
