Thanks Michael. 

Let me put my spin on what I think you said:

    Each element and attribute that is declared in an XML Schema 
    document acquires a namespace property by virtue of the presence 
    of the targetNamespace attribute on the xs:schema element.

Is that correct?

This is an embarrassingly simple question: 

    A namespace is a "property" is an element. Yes? 

I've never thought of a namespace as being a "property" of an element. What other "properties" do element's have? If an element has attributes, are those attributes a "property" of the element?

targetNamespace is a property of a schema component which it acquires by 
virtue of the presence of a targetNamespace attribute on the xs:schema 
element of the schema document in which the XML representation of the 
component appears.

Which is a mouthful, but to make it fit to go into the spec you would 
have to add appropriate fonts, brackets, and braces.

But the important thing to note is that targetNamespace is not a 
property of a schema, it is a property of a schema document.
