Bug 176436 Charts Imported from Libraries do not update when libraries change
During a live presentation of BIRT at EclipseCon, we came across a rather embarassing issue. When charts are included in a library, and imported into a report design from a library, any changes to the library instance of the chart do not reflect in the report itself.
model/org.eclipse.birt.report.model.tests/test/org/eclipse/birt/report/model/library/ReloadLibraryTest.java
* <p>
	 * The structure is synchronized with table in library. Local values of
	 * virtual elements are kept.
	 * <p>
	 * <strong>Case2:</strong>
	 * <p>
	 * lib1.theme1.style1
	 * <p>
	 * If style is removed, the design can only find the style name, not style
	 * instance.
	 * <p>
	 * <strong>Case3:</strong>
	 * <p>
	 * name space
	 * <p>
	 * If the libTable1 drops 2 rows, Designl.table1 will not see these rows any
	 * more. And names of report elements in these rows are removed from the
	 * namespace.
	 * <p>
