Loukik,

Just some additional thoughts.

First I created Storage Manager in Components architecture because of 
performance. But as I tested later, the performance was exactly the 
same, so using component is unnecessary complication.

The simplest way of using Storage Manager is the way I followed in the 
LS. (XmlLsTypeServiceEngine.java).

I left old functionality to avoid crash of other services that used this 
 Storage Manager. But I think we should migrate towards using Storage 
Manager directly

I agree, that properties names should be unified, but it may be not so 
simple, especially if you need to use different Storage Managers 
(probably there would be a need for using it in LS when we had AA)

But,as I told you by phone: I agree it could be done better. I'll talk 
to Roman about it and we'll find a consensus :)
