[Product-Developers] what goes in layer attribute when extending IBrowserLayerAwareExtender?

[Dylan Jay]

Hi,

I can't find doctests or documentation and so far experimenting hasn't 
resulted in a working schemaextener.

The code I have looks like this

class PublicationExtender(object):
     adapts(ATFile)
     implements(IBrowserLayerAwareExtender)

     layer = "pretaweb.publayer"


I've also tried setting the layer attribute to be the interface of the 
layer. What is it supposed to be?

Dylan.
