// aimsClassRender.js
/*
*  JavaScript template file for ArcIMS HTML Viewer Interactive Class Rendering
*		dependent on aimsXML.js, aimsDHTML.js, aimsCommon.js, and ArcIMSparam.js, 
*
*	Functions to change elements in the LayerRenderString array, whose elements are
*		strings containing replacement renderer arcxml tags for a specific layer for 
* 		current map request
* 	The element index is the Layer's index, starting with the topmost layer as zero.
*		The string must contain the complete renderer information for the layer 
*		(including any labelling or scaling) and follow arcxml renderer requirements.
*
*
*
ClassRender parameters:
These override the layer's default renderer. A sample custom JavaScript library 
aimsClassRender.js, found in the HTML Viewer Samples, can be used to interactively 
change these values.

ClassRenderLayer (Array/Dynamic):
Array of layer names for custom class rendering.  Overrides default renderer. 
Each element must have corresponding element in the ClassRenderString array.

ClassRenderString (Array/Dynamic):
Array of custom render parameters for custom class rendering. Overrides default renderer. 
Each element must have corresponding element in the ClassRenderLayer array.

Example:
ClassRenderLayer [0]=" Cities";
ClassRenderString [0]="";

If string is not empty string, default rendering is overridden with string.
