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.

				writer.textCDATA( value );
			else
				writer.text( value );

		{
			for ( int i = 0; i < children.size( ); i++ )
			{
				ContentNode child = (ContentNode) children.get( i );
				writeContentNode( child );
			}
		}
		writer.endElement( );
