But then we have a slightly different problem. Developers who try to do 
the right thing will be hit by interoperability issues. Either that or 
they have to specify a particular (set of) SAX implementation(s) which 
somewhat undermines SAX as a common API.

On reflection, I think that SAX should be tweaked to at least require 
support for this feature, and maybe mandate that the default be to not 
retrieve external entities.
