 * This test demonstrates how the Spring 3.1
 * PropertySourcesPlaceholderConfigurer treats the local-override property
 * differently than the PropertyPlaceholderConfigurer.
 * 
 * This test uses two application contexts that are identical except for the
 * Spring schema locations (PropertyPlaceholderConfigurer-context.xml uses
 * *-3.0.xml whereas PropertySourcesPlaceholderConfigurer-context.xml uses
 * *-3.2.xml).
