SPR_20004_1 incorrectly documents the conformance item it is designed to test in context.xml:

Tests that the value of the @name attribute of an <sca:reference/> subelement of a <beans/> element 
is unique amongst the @name attributes of the <reference/> subelements, <property/> subelements 
and the <bean/> subelements of the <beans/> element.

Instead, per the Spring C&I Specification, it should be testing:

The @default attribute of a <reference/> subelement of a <beans/> element MUST have the value of the @name attribute of one of the <bean/> subelements of the <beans/> element.
