Christophe Lombart resolved JCR-1467.
-------------------------------------

    Resolution: Fixed

I made patch. Can you check it ? 

It is no longer necessary to use the ocm namespace and the ocm:discriminator 
mixin type. 

Here is a summary of the current situation  : 

1. If the jcr node type is map to only java class, it is always possible to 
find the class name to instantiate. So, a discriminator (an extra property 
which will contains the class name) is not necessary.

2. if the same node type is mapped to different java classes, we have different 
situations : 
 
a. If the class is mapped to the unstructured node type or a node type
that gives you  the possibility to add extra properties, OCM will create a new
property "ocm_classname".
b. If it  is not possible to add this property due to strong constrains in the 
corresponding node type, OCM will try to add the mixin type "ocm:discriminator".
