I thought I was using a good tutorial, 'Building Web Services with Java',
and amazon reviewers praised this book but it appears to have many errors.

The snippet below had 'po' in front of 'billTo', 'shipTo', 'order', etc. but
they say by moving the 'po' namespace definition to the 'po:po' element, the
child elements fall into that namespace:

'We can use this to further clean up the composed XML document
by moving the PO namespace declaration to the po element
