Sorry to take so long to get back to you.

The 'name' attribute on <xsd:simpleType> is scoped to its element and
is therefore in the "http://www.w3.org/1999/XMLSchema" namespace. 
Unprefixed attributes are always scoped to their elements. You'll note
that in Section 5.2 of XML Namespaces "[...] default namespaces do not
apply directly to attributes."
