---+ Proposed Errata

---++ Query in 10.7 "Records from Registry"

---+++ Suggested Text

The exampe in section 10.7, "Records from Registry" should read

<verbatim>
SELECT ivoid FROM rr.resource
RIGHT OUTER JOIN (
  SELECT 'ivo://' || detail_value || '%' AS pat
  FROM rr.res_detail
  WHERE detail_xpath='/managedAuthority' 
    AND ivoid='ivo://cds.vizier/registry') 
  AS authpatterns
ON (1=ivo_nocasematch(resource.ivoid, authpatterns.pat))
</verbatim>


---+++ Rationale

As values in res_detail are no longer case-normalized (as they had been when
the example query was written), the query as given in the REC-1.0 will not
yield results for mixed-case authorities (and as it happens, the authorities in
the examples are all mixed case).  The proposed new query works regardless
of authority case.

---+++ Impact assessment

As no normative text is changed, implementations are not concerned.  
Persons trying the example queries will be spared debugging.
