Clarification needed "under the name of a dataset": my guess is that we can 
configure in Heron a legend URL with an OL Layer instance ?

e.g. 

      new OpenLayers.Layer.WMS("MyLayer",
            'http://mywms.com/wms',
    {layers: "mylayername", format: "image/png", transparent: true},
    {isBaseLayer: false, singleTile: true,  visibility: false, legendURL='http://mylegends.com/mylayer.gif'}
    )

Ok. To make things clear and break up functionalities:

- allow for custom Legend URL (i.s.o. WMS GetLegend)
- Legend image within layer tree

Maybe we could choose between gx_urllegend (TMS, XYZ, TileCache), gx_wmslegend 
(WMS) and gx_vectorlegend (vectors) dynamically in hr_layerlegendpanel?

- allow for custom Legend URL (i.s.o. WMS GetLegend) is now (v0.74)  supported 
via Patch from Martin in issue 255.
works for all Layer types and even printing e.g. TMS by onfiguring legendURL 
custom Layer property.

In the context of issue 331 quite some work has been done. See the examples:

http://lib.heron-mc.org/heron/latest/examples/sublayers and

http://lib.heron-mc.org/heron/latest/examples/layertree

It is now possible to configure legends in the LayerTree in two ways by 
configuring the 'nodeType: "gx_layer" entries:

- by explicitly setting the 'text' to with an HTML img with custom image or WMS 
GFI request

             {nodeType: "gx_layer", layer: "USA States (population < 2M)", text: Heron.options.legendImages.l_lt2M + "Population < 2M", legend: false },

- by setting the legend: true property: a GeoExt LayerLegend (WMS or Vector 
Legend Panel) is inserted:

        {nodeType: "gx_layer", layer: "USA States (All)", text: "USA States WMS (All)", legend: true},

See example attachment. I think this issue is fixed and can be closed...
