057     * Represents an <code>Update</code> operation as a part of a {@link Transaction} request.
058     * <p>
059     * WFS Specification OBC 04-094 (#12.2.5 Pg.68)
060     * <p>
061     * The <code>Update</code> element describes one update operation that is to be applied to a <code>Feature</code> or
062     * a set of <code>Feature</code>s of a single <code>FeatureType</code>.
063     * <p>
064     * Multiple <code>Update</code> operations can be contained in a single <code>Transaction</code> request. An
065     * <code>Update</code> element contains one or more <b>Property</b> elements that specify the name and replacement
066     * value for a property that belongs to the <code>FeatureType</code> specified using the <b>mandatory typeName</b>
067     * attribute.
068     * <p>
069     * Additionally, a deegree specific addition to this specification is supported:<br>
070     * Instead of a number of properties, it is also possible to specify a root feature that will replace the feature that
071     * is matched by the filter. In this case, the filter must match exactly one (or zero) feature instances.
