Having dug deeper ( I read the docs :-) )...

I needed to register an error handler to get errors reported.

Xerces complains that;

    Element type "person" must be declared.

which is the same as MSXML. I'm reading this as 'I found an element called
person that I was not expecting'. It's a pity that neither MSXML nor Xerces
give namespace information along with the local names in these error
messages.

Changing the instance to use prefix f for the 'friends' namespace give the
following error;

Datatype error: In element 'date' : Value '1990/09/28' is not legal value
for current datatype.

Fixing the instance to be;

<?xml version="1.0" encoding="UTF-8"?>
<f:friend xmlns:f="http://redrice.com/friends"
        xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
  xsi:schemaLocation='http://redrice.com/friends friend.xsd
http://redrice.com/birthdays birthday.xsd'>
  <b:birthdays xmlns:b="http://redrice.com/birthdays">
    <person>fred</person>
    <date>1990-09-28</date>
  </b:birthdays>
</f:friend>

and everything validates just fine which is what I would expect per the
spec.

Cheers

Gudge
