/**
* The document handler that receives parse events that an XML parser sends while it
* is parsing an XML document representing a <code>WebRowSet</code> object. The
* parser sends strings to this <code>XmlReaderContentHandler</code> and then uses
* these strings as arguments for the <code>XmlReaderContentHandler</code> methods
* it invokes. The final goal of the SAX parser working with an
* <code>XmlReaderContentHandler</code> object is to read an XML document that represents
* a <code>RowSet</code> object.
* <P>
* A rowset consists of its properties, metadata, and data values. An XML document
* representating a rowset includes the values in these three categories along with
* appropriate XML tags to identify them. It also includes a top-level XML tag for
* the rowset and three section tags identifying the three categories of values.
* <P>
* The tags in an XML document are hierarchical.
* This means that the top-level tag, <code>RowSet</code>, is
* followed by the three sections with appropriate tags, which are in turn each
* followed by their constituent elements. For example, the <code>properties</code>
* element will be followed by an element for each of the properties listed in
* in this <code>XmlReaderContentHandler</code> object's <code>properties</code>
* field. The content of the other two fields, <code>colDef</code>, which lists
* the rowset's metadata elements, and <code>data</code>, which lists the rowset's data
* elements, are handled similarly .
* <P>
* This implementation of <code>XmlReaderContentHandler</code> provides the means for the
* parser to determine which elements need to have a value set and then to set
* those values. The methods in this class are all called by the parser; an
* application programmer never calls them directly.
