  Because the document is well-formed. So the data can be interpreted by the
user application. Validation is an optional feature, you need to turn it
on at the parser level, it will still give back a document, but you will
get validation errors. This behaviour is directly derived from the W3C 
Recommendation defining XML, see well-formedness , fatal error, and
validity constraints definitions in the spec.
