The XML spec also says: "It is an *error* for a fragment identifier

What is an error? The spec defines it as: "a violation of the rules 
of this specification; results are undefined. Unless otherwise 
specified, failure to observe a prescription of this specification 
indicated by one of the keywords MUST, REQUIRED, MUST NOT, SHALL and 
SHALL NOT is an error. Conforming software MAY detect and report an 
error and MAY recover from it." [1] The spec doesn't compel a parser 
to detect errors (besides violations of validity constraints, 
reported at user option), nor does it specify how a parser recovers 
if it chooses to.


However, the SAX spec says that such errors correspond to calls to 
the error() method in the registered ErrorHandler, if any. I think it 
should be reported if the user has installed an error handler. 
Silently throwing away data is a bad thing.
