Hello David, The error being reported is in accordance with the original schema rec [1], however an erratum [2] was issued allowing the length facet to be specified on a different derivation step than minLength/maxLength. We're aware of this discrepancy, but haven't fixed it yet. (By the way, this doesn't concern 'fixed' on minLength which prevents a derivation step from respecifying that facet again with a different value.) If you'd like to open a bug report, please do.
Thanks.
