Hi Adrian,
/code will point to a node in the document which is used for context for the expression. E.g. the document will be determined by the node from instance('observations')/data, so if you expected that /code would always go to the default instance then that would not be true. You must in such a case move the context back to the default instance using the instance() function, e.g.
instance('observations')/data[instance('default') != 'foo']
Best regards,
David

Does the instance() function change the context node?
eg, if I have the following xpath expression
instance('observations')/data[/code != 'foo']
What should /code within the predicate be evaulated against ?
