Thanks for your endorsement, but XSV is not the gold standard -- as
the status page [1] makes clear, there are implementation gaps and
known bugs, to say nothing of unknown bugs.

There are invalid _as named group definitions_. With named groups, we
had a choice:
1) Allow min/max both on the reference and the definition;
2) Allow min/max both only on the reference;
3) Allow min/max both only on the definition.
We chose (2). Sorry for the confusion.
