-/**
- * A dialog where one input element can be compared against
- * a list of historic variants (editions) of the same input element.
- * The dialog can be used to implement functions like "Compare/Replace with Version" or
- * "Compare/Replace from Local History" on workspace resources.
- * <p>
- * In addition it is possible to specify a subsection of the input element
- * (e.g. a method in a Java source file) by means of a "path".
- * In this case the dialog compares only the subsection (as specified by the path)
- * with the corresponding subsection in the list of editions.
- * Only those editions are shown where the subsection differs from the same subsection in
- * another edition thereby minimizing the number of presented variants.
- * This functionality can be used to implement "Replace from Local History"
- * for the Java language.
- * <p>
- * Subsections of an input element are determined by first finding an
- * <code>IStructureCreator</code> for the input's type.
- * Then the method <code>locate</code> is used to extract the subsection.
- * <p>
- * Each edition (variant in the list of variants) must implement the <code>IModificationDate</code> interface
- * so that the dialog can sort the editions and present them in a tree structure where every
- * node corresponds one day.
- * <p>
- * The functionality is surfaced in a single function <code>selectEdition</code>.
- * <p>
- * Clients may instantiate this class; it is not intended to be subclassed.
- * </p>
- *
- * @see IModificationDate
- * @see ITypedElement
