Structure members use a different XML namespace for each schema, but
these namespaces are not entirely consistent: in some SPV files, for
example, the @code{viewer-tree} schema is associated with namespace
-@indicateurl{http://xml.spss.com/spss/viewer-tree} and in other with
+@indicateurl{http://xml.spss.com/spss/viewer-tree} and in others with
@indicateurl{http://xml.spss.com/spss/viewer/viewer-tree} (note the
-additional @file{viewer/} directory. In any case, the schema URIs are
+additional @file{viewer/}). In any case, the schema URIs are
not resolvable to obtain the schemas themselves.
One may ignore all of the above in interpreting a structure member.
