OK, then the piece you're missing is that global element declarations (
those that are children of a schema element ) are in the targetNamespace
regardless of the value of elementFormDefault. Local element declarations
( those that are *not* children of a schema element ) are only in the
targetNamespace if they are themselves annotated with form='qualified' or,
if they do not have a form attribute, the elementFormDefault attribute on
the ancestor schema element has the value 'qualified'

The relevant bits of the spec are in 3.3.2[1]. There are two descriptions of
the {target namespace} property; one for element declarations that have
schema as a parent;

The ·actual value· of the targetNamespace [attribute] of the parent <schema>
element information item, or ·absent· if there is none.

and another for element declarations that are part of complex type
defintions;

If form is present and its ·actual value· is qualified, or if form is absent
and the ·actual value· of elementFormDefault on the <schema> ancestor is
qualified, then the ·actual value· of the targetNamespace [attribute] of the
parent <schema> element information item, or ·absent· if there is none,
otherwise ·absent·.
