/**
* Sets this <code>XmlReaderContentHandler</code> object's <code>tag</code> field if the given
* name is the key for a tag and this object's state is not <code>INITIAL</code>. The field is set
* to the constant that corresponds to the given element name. If the state is <code>INITIAL
* </code>, the state is set to the given name, which will be one of the sections <code>PROPERTIES
* </code>, <code>METADATA</code>, or <code>DATA</code>. In either case, this method puts this
* document handler in the proper state for calling the method <code>endElement</code>.
*
* <p>If the state is <code>DATA</code> and the tag is <code>RowTag</code>, <code>DelTag</code>,
* or <code>InsTag</code>, this method moves the rowset's cursor to the insert row and sets this
* <code>XmlReaderContentHandler</code> object's <code>idx</code> field to <code>0</code> so that
* it will be in the proper state when the parser calls the method <code>endElement</code>.
