Hello,

My head is sore from bashing it against a brick wall so I hope someone can
help me with this!

Below is some XML, a schema and the output from XSV when I try to validate.

I am trying to express a key/keyref constraint but I always get an XSV
error.  I have tried altering the position of the xsd:keyref and xsd:key
elements in case it is some sort of scoping problem but with no success.

(I have also tried the example from section 5 of the primer (4Q99.xml and
report.xsd) and I get the same error, although I admit I did change
report.xsd by removing the import and changing 'xipo:SKU' to 'string'!)

Could someone please explain to me what I'm doing wrong?

Many thanks,
Adam
