Hi,
  I am trying to implement a custom form control and I see that the samples of the SDF contains the java source of the SimpleURLChooserEditor. 
  However, I don't see anything in the SDF css calling it like it mentions in the dev guide - "http://www.oxygenxml.com/doc/ug-editor/topics/implementing-custom-form-controls.html". 
I saw the blog post at "http://blog.oxygenxml.com/" but that did not clarify things for me. 
  It would be great if I could get step-by-step instructions on how to do this.

Thanks,
Nathan
