This example focusses on a more verbose description of WMS layers. See also the basic WMS example, please.
The example shows how to use a combination of your own textualDescriber which generates actual HTML from the details gathered for each layer together with manually setting an approriate
ARIA property aria-describedby instead of default aria-description.
Since the focus of this example is on the layers, zooming and panning of the map does not change the description.
