defining a new primary node type on a fly

[Dimitar Dimitrov]

Hi guys.
I am trying to import new node type definition by CND on a fly.
We develop a Adobe Flex based interface which can build CND by 
hierarchical UI and I want to import this new node type into the JCR 
repository.
For now when I want to import new node type definition I make a new OSGI 
Sling bundle and import the schema into it.
Is there another way to importing the newly generated CND into the 
repository and start using it immediately.

Thanks in advance.
