The problem is that XML filters can and routinely do violate 
well-formedness constraints, even when the underlying real parser does 
not. I special case one common filter that I trust not to violate XML's 
well-formedness rules (Norm Walsh's catalog filter) but I'm not willing 
to extend this courtesy to all filters everywhere.
