[xquery-talk] Results with distinct-values varies dependent on syntax

[Ihe Onwuka]

xquery version "3.1";

let $schemaCollection := "/db/apps/schemas"
 return
collection($schemaCollection)/xs:schema/distinct-values(@targetNamespace)

does not eliminate duplicates

xquery version "3.1";

let $schemaCollection := "/db/apps/schemas"
 return collection($schemaCollection)/xs:schema/@targetNamespace =>
distinct-values()

does.

I checked this in Saxon and exist-db XQuery, both return the same results
so this may be how it's supposed to work but I don't get it.
