----------------------------------------
Each attribute for all built-in types must have default values. (from here: 
http://docs.puppetlabs.com/references/3.stable/type.html)

It's very important when you wrap some type with parametrized class/defined 
type. I that case you should pass parameters from container to wrapped type. So 
you must know default values for all type's attribute to add then as default 
values for class/defined type.

E.g. you has standard package->config->service parametrized class. You want to 
add enable and ensure attributes of service to main class:

class someclass (
  $ensure = ????,
  $enabled = ????,
  ...
) {

service {'someservice':
  ensure => $ensure,
  enabled => $enabled,
  ...

Now you can't simply use default values of attributes from service to class, 
because there is no default values. So behavior of whole class differs from 
behavior of a service. And so there is a lot of problems in large installations.

See http://projects.puppetlabs.com/issues/22580 - here is one of examples.
