it gets very difficult to follow what is being said when the same name is
being used for two separate things, one an element and another a
complexType.

it seems to me that:

1) the "given" and "family" elements _are not_ locally scoped to the
"person" element.

this is completely akin to:

<!ENTITY % person.model "(given,family)">
<!ELEMENT given (#PCDATA)>
<!ELEMENT family (#PCDATA)>

<!ELEMENT person %person.model;>

in this case I can also do:

<!ELEMENT another.person %person.model;>

similarly

<xs:element name="another.person" type="this:person"/>

2) it also looks like all these elements are in the same namespace (as I
suggested).
