	 * We fabricates 3 element( ElementA, ElementB and ElementC) and 5 property
	 * definitions(P1,P2,P3,P4,P5) and 2 user property definitions(UP1,UP2).
	 * Apply property on elEments as:
	 * <p>
	 * 1.
	 * <ul>
	 * <li>ElemnetA(P1,P2,P3,P4,P5).</li>
	 * <li>ElemnetB(P1,P2,P3).</li>
	 * <li>ElemnetC(P3,P4,P5).</li>
	 * </ul>
