Entities and non-validation

[David Brownell]

Good catch.

When the nonvalidating parser ignored one or more external PEs,
this isn't a fatal error.  SAX2 (alpha still) has ways to report
the situation, as I noted elsewhere in my response.

My general advice is still to avoid nonvalidating parsers that
don't read external entities, since the failure modes get so
confusing.
