Keith,
I am pretty fresh to this myself, but my understanding (gleaned from
Arnaud) is;
marshalling validation turns on grammer and lexical checking of the xml
during marshalling and unmarshalling. this checking is performed with
the help of the castor class descriptors.
parser validation causes a sax parser (xerces??) to be run over the xml.
i don't know exactly when it is run.
my understanding is, that if you want to perform your validation upon
marshalling and unmarshalling of your xml data, that you should only
need to turn on marshalling validation. that said, i have some unit
tests upon which castor marshalling validation does not pick up some
errors in xml data. some situations where i have errors that go
undetected are;
(*) boolean attribute value that is not "true", "false", 1 or 0.
(*) choice of mandatory elements where no elements are present.
(*) element with a value for a prohibited attribute
mind you, i think the intalio guys have done an amazing amount of work
for which i am grateful and i am sure that these issues will get
addressed in due time.
hope this helps a little :-)
Regards,
Dave Young.
