/**
* The standard interface that all implementations of a <code>WebRowSet</code>
* must implement.
* <P>
* <h3>1.0 Overview</h3>
* The <code>WebRowSetImpl</code> provides the standard
* reference implementation, which may be extended if required.
* <P>
* The standard WebRowSet XML Schema definition is available at the following
* URI:
* <ul>
* <pre>
* <a href="http://java.sun.com/xml/ns/jdbc/webrowset.xsd">http://java.sun.com/xml/ns/jdbc/webrowset.xsd</a>
* </pre>
* </ul>
* It describes the standard XML document format required when describing a
* <code>RowSet</code> object in XML and must be used be all standard implementations
* of the <code>WebRowSet</code> interface to ensure interoperability. In addition,
* the <code>WebRowSet</code> schema uses specific SQL/XML Schema annotations,
* thus ensuring greater cross
* platform inter-operability. This is an effort currently under way at the ISO
* organization. The SQL/XML definition is available at the following URI:
* <ul>
* <pre>
* <a href="http://standards.iso.org/iso/9075/2002/12/sqlxml">http://standards.iso.org/iso/9075/2002/12/sqlxml</a>
* </pre>
* </ul>
* The schema definition describes the internal data of a <code>RowSet</code> object
* in three distinct areas:
* <UL>
* <li><b>properties</b></li>
* These properties describe the standard synchronization provider properties in
* addition to the more general <code>RowSet</code> properties.
* <p>
* <li><b>metadata</b></li>
* This describes the metadata associated with the tabular structure governed by a
* <code>WebRowSet</code> object. The metadata described is closely aligned with the
* metadata accessible in the underlying <code>java.sql.ResultSet</code> interface.
* <p>
* <li><b>data</b></li>
* This describes the original data (the state of data since the last population
* or last synchronization of the <code>WebRowSet</code> object) and the current
* data. By keeping track of the delta between the original data and the current data,
* a <code>WebRowSet</code> maintains
* the ability to synchronize changes in its data back to the originating data source.
* </ul>
* <P>
* <h3>2.0 WebRowSet States</h3>
* The following sections demonstrates how a <code>WebRowSet</code> implementation
* should use the XML Schema to describe update, insert, and delete operations
* and to describe the state of a <code>WebRowSet</code> object in XML.
* <p>
* <h4>2.1 State 1 - Outputting a <code>WebRowSet</code> Object to XML</h3>
* In this example, a <code>WebRowSet</code> object is created and populated with a simple 2 column,
* 5 row table from a data source. Having the 5 rows in a <code>WebRowSet</code> object
* makes it possible to describe them in XML. The
* metadata describing the various standard JavaBeans properties as defined
* in the RowSet interface plus the standard properties defined in
* the <code>CachedRowSet</code><sup><font size=-2>TM</font></sup> interface
* provide key details that describe WebRowSet
* properties. Outputting the WebRowSet object to XML using the standard
* <code>writeXml</code> methods describes the internal properties as follows:

* Having detailed how the properties and metadata are described, the following details
* how the contents of a <code>WebRowSet</code> object is described in XML. Note, that
* this describes a <code>WebRowSet</code> object that has not undergone any
* modifications since its instantiation.
* A <code>currentRow</code> tag is mapped to each row of the table structure that the
* <code>WebRowSet</code> object provides. A <code>columnValue</code> tag may contain
* either the <code>stringData</code> or <code>binaryData</code> tag, according to
* the SQL type that
* the XML value is mapping back to. The <code>binaryData</code> tag contains data in the
* Base64 encoding and is typically used for <code>BLOB</code> and <code>CLOB</code> type data.

* <h4>2.2 State 2 - Deleting a Row</h4>
* Deleting a row in a <code>WebRowSet</code> object involves simply moving to the row
* to be deleted and then calling the method <code>deleteRow</code>, as in any other
* <code>RowSet</code> object. The following
* two lines of code, in which <i>wrs</i> is a <code>WebRowSet</code> object, delete
* the third row.
* <PRE>
* wrs.absolute(3);
* wrs.deleteRow();
* </PRE>
* The XML description shows the third row is marked as a <code>deleteRow</code>,
* which eliminates the third row in the <code>WebRowSet</code> object.

* <h4>2.3 State 3 - Inserting a Row</h4>
* A <code>WebRowSet</code> object can insert a new row by moving to the insert row,
* calling the appropriate updater methods for each column in the row, and then
* calling the method <code>insertRow</code>.
* <PRE>
* wrs.moveToInsertRow();
* wrs.updateString(1, "fifththrow");
* wrs.updateString(2, "5");
* wrs.insertRow();
* </PRE>
* The following code fragment changes the second column value in the row just inserted.
* Note that this code applies when new rows are inserted right after the current row,
* which is why the method <code>next</code> moves the cursor to the correct row.
* Calling the method <code>acceptChanges</code> writes the change to the data source.
*
* <PRE>
* wrs.moveToCurrentRow();
* wrs.next();
* wrs.updateString(2, "V");
* wrs.acceptChanges();
* :
* </PRE>
* Describing this in XML demonstrates where the Java code inserts a new row and then
* performs an update on the newly inserted row on an individual field.

* <h4>2.4 State 4 - Modifying a Row</h4>
* Modifying a row produces specific XML that records both the new value and the
* value that was replaced. The value that was replaced becomes the original value,
* and the new value becomes the current value. The following
* code moves the cursor to a specific row, performs some modifications, and updates
* the row when complete.
* <PRE>
* wrs.absolute(5);
* wrs.updateString(1, "new4thRow");
* wrs.updateString(2, "IV");
* wrs.updateRow();
* </PRE>
* In XML, this is described by the <code>modifyRow</code> tag. Both the original and new
* values are contained within the tag for original row tracking purposes.
