Hi,

Could someone explain this a bit further or point me at an appropriate
resource. What does someone have to do, with XML, to be able to identify how
metadata is marked-up? I am guessing you have to use the string
"http://whatever/foo.xsd", but surely the metadata schema can be changed
(which would break everything)?

All the best,
Tim.
