match="*[namespace-uri-from-QName(resolve-QName(@mode, .)) eq
'urn:item-namespace-1.0']"

will compare the namespaces regardless of prefix

alternatively, get all of the in-scope-prefixes(), loop through them
and get the namespace-uri-for-prefix() to find the one bound to that
namespace, then just check the value of @mode (eg name() eq
'b:blip')... but I'm not sure you need to worry about the actual
prefix in this case?
