This is an area that I (and I think others) have difficulty with, although
I think there are many who are clear how different parsers behave. This
also interacts with the 'standalone' value in the xml PI. There is also
some potential confusion as to when and how the presence/absence of the
external subset makes a difference.
If my worries are unfounded, then it should be possible to create a precise
description of what parameters, files, internal subsets etc. and need to
control the behaviour of a SAX-compliant parser and what it should do. In
which case it would be very helpful to see it set out clearly and I'll shut
up. If, however, there still is confusion then we shall discover it in
these attempts :-)
