Puppet users - Jul 2010 - 2.6, parameterized classes, external nodes

The release notes do not mention whether the external node classifier
system now supports parameterized classes, and if so, what the syntax
expected would be to use it.  Is this supported?

Also, the release notes indicate with respect to parameterized classes:
"with the significant difference that definitions have multiple
instances whilst classes remain singletons."

Many of us have the problem of needing to simulate the instantiation of
definitions via external nodes (e.g., the multiple Apache vhosts
situation, or multiple service instantiations with unique
configurations).  Since these are singletons, I''m guessing
parameterized
classes won''t help in solving this problem...  Does 2.6 provide any new
support toward solving it?

Thanks.
-Alan

Now I''m confused.  Isn''t a parameterized class the same as a
define except for the class being a singleton?

So what does that mean exactly?  Can you do:
class { myclass: name => "foo", myval => "one" }
class { myclass: name => "baz", myval => "two" }

And instantiate a set of unique resources?
