<DL>
<DD>Encoding of cell hierarchies is built-into the core, but is a
 higher-level function that needs to be explicitely used by the
 respective object encoders (eg. mxModelCodec, mxChildChangeCodec
 and mxRootChangeCodec). This implementation writes the given cell
 and its children as a (flat) sequence into the given node. The
 children are not encoded if the optional includeChildren is false.
 The function is in charge of adding the result into the given node
 and has no return value.

<DT><B>Parameters:</B><DD><CODE>cell</CODE> - mxCell to be encoded.<DD><CODE>node</CODE> - Parent XML node to add the encoded cell into.<DD><CODE>includeChildren</CODE> - Boolean indicating if the method
 should include all descendents.</DL>

 that represents the given node.
