It doesn't know or distinguish. In my client's case, it merely reads
from a WMC:
- Layer/Title
-
Layer/StyleList/Style(current="1")/LegendURL/OnlineResource/@xlink:href
...and prints out a table construct like:
<table>
<tr>
<td><img src="SomeGetLegendGraphicRequest"></td>
<td>SomeLayerTitle</td>
</tr>
...
</table>
i.e. check out http://cgdi-dev.geoconnections.org/prototypes/owsview/,
and click the "legend" looking icon in the left frame above the layer
select box. You'll see what I'm talking about.
