/**
* This class represents a light-weight DOM model for simple result tree fragment(RTF).
* A simple RTF is an RTF that has only one Text node. The Text node can be produced by a
* combination of Text, xsl:value-of and xsl:number instructions. It can also be produced
* by a control structure (xsl:if or xsl:choose) whose body is pure Text.
* <p>
* A SimpleResultTreeImpl has only two nodes, i.e. the ROOT node and its Text child. All DOM
* interfaces are overridden with this in mind. For example, the getStringValue() interface
* returns the value of the Text node. This class receives the character data from the
* characters() interface.
* <p>
* This class implements DOM and SerializationHandler. It also implements the DTM interface
* for support in MultiDOM. The nested iterators (SimpleIterator and SingletonIterator) are
* used to support the nodeset() extension function.
