Your note of 4/12 reproduced below confuses me.
keyref fields can only refer to key fields and these are, by definition,
non-nullable.

All the best, Ashok

=============================
Not key, but keyref, for a change.
Seems to me we missed a case: if the node picked out by a keyref's field is
xsi:null='true', then this should be
treated as if the node had not been found. As the PWD reads, it will just
use an empty string as that field's
contribution to the key sequence to be looked up.
Ditto for unique fields.
