[Zope-dev] What is that? (ZPatterns)

[Mike]

class Foo( RackMountable) :
  def bar( self) :
    print self.propertysheets.items()

in live system bar always will print "[('webdav', )]". I see there is a
default propertysheet 'webdav' in each RackMountable instance. Where
come that 'webdav' from and what is it for?

Thanks,
Mike
