Укрощение Advanced Find, часть 1

/// Summary:
/// Provides a mechanism for replacing the contents of any Iframe on an entity form
/// with any Advanced Find view.
///
/// Param Description
/// ---------- -------------------
/// iFrameId The id established for the target Iframe
/// entityName The name of the entity to be found by the Advanced Find
/// fetchXml FetchXML describing the query for the entity
/// layoutXml LayoutXML describing the display of the entity
/// sortCol The schema name of the entity attribute used for primary sorting
/// sortDescend "true" if sorting the sortCol by descending values, or "false" if ascending
/// defaultAdvFindViewId The GUID of an Advanced Find View for the entity; may that of a saved view
/// entityTypeId (Optional) The Object Type ID for the entity. Setting this causes the system
/// to overwrite the functionality of the "New" button to establish related records
