046 * Represents a <code>Replace</code> operation as a part of a {@link Transaction} request.
047 * <p>
048 * This operation is designed after the Replace operation of the upcoming WFS 2.0.0 specification. One or more feature
049 * instances (specified by a filter expression) are replaced by a given feature instance. The replacement is assumed to
050 * be performed property by property, so the targeted features are identical to the specified feature afterwards, but
051 * keep their original feature ids.
