How to tag a particular version in jackrabbit / JCR?
===

I want to know if I can tag a particular version. 
 I want to use JCR in my project and we have many hierarchical type tree made of different type of nodes and we need to save a version after bunch of changes for staging or production. I want to know how can I tag the particular version  so that all the changes made for particular node and its children will be saved. 

Thanks!!!
