Background
The dialog launched from the View->Query->New Query menu entry allows the user to construct a query that will locate objects in the structure that match the specified criteria. The out-of-the-box configuration allows specific attributes of WTPart to be queried.
Customers will create their own subtypes of WTPart with their own attributes. In order to allow these to be used in the query, customization of the PSE XML files is required.
