Create KML document
Generating KML is pretty easy using TOS XML output component.
In this example, we're using rows generator to create information, but you could use text file with lat, lon coordinates, or point geometry shapefiles as well.
Description field could contain HTML. For example:
<h1>Title</h1> More info <a href='http://somesite'>here</a>
