Bug 209106 BIRT - User properties defined in a library are not seen in properties view
In the attached library there is a grid container. The text control and the row of the table in the grid have two user properties each. We can see them in the library but not when we drag them in to a design. The property does not show up in the properties view

* <p>
 * <ul>
 * <li>The {@link #setExtendsElement}method sets the parent element.</li>
 * <li>The {@link #setExtendsName}method sets the name of the parent element.
 * It is used when reading a design file, or if it is necessary to store an
 * unresolved parent name.</li>
 * <li>The {@link #getExtendsElement}method gets the parent element.</li>
 * <li>The {@link #extendsRef}member stores the reference to the parent
 * element.</li>
 * </ul>
 * 
 * <h3>User-Defined Properties</h3>
 * 
 * As noted above, the user can define user-defined properties for an element.
 * User-defined properties have many of the same attributes as system-defined
 * properties. User-defined properties work virtually the same as system-defined
 * properties, including support for localization, for a property type, for
 * validating the property value, and more.
 * <p>
 * Members and classes in the user-defined property system include:
 * <p>
 * <ul>
 * <li>The {@link #addUserPropertyDefn}method defines a user-defined property.
 * </li>
 * <li>The {@link #dropUserPropertyDefn}method removes a user-defined
 * property.</li>
 * <li>The {@link #getUserPropertyDefn}method gets the definition of a
 * user-defined property.</li>
 * <li>The {@link UserPropertyDefn}class defines a user-defined property.
 * </li>
