I am mainly familiar with XML Schema 1.0, so it's possible my assertions below have been supplanted in 1.1.
The purpose of a schema is to declare the contents of a single namespace, the target namespace, which is declared on the 'schema' element. Constructs of another namespace cannot be declared in this schema; they can only be referenced, using qualified names. So <element name="xyz" ...> declares an element in the target namespace. <element ref="other:abc" ...> refers to a global element in the namespace declared to correspond to the prefix "other".
