Michael Dürig commented on OAK-169:
-----------------------------------

Support for (efficient) stable order would require support from the 
Microkernel. But exactly this was removed in [Revision 
1234198|http://svn.apache.org/viewvc/jackrabbit/oak/trunk/oak-mk/src/main/java/org/apache/jackrabbit/mk/model/ChildNodeEntriesMap.java?r1=1234021&r2=1234198&diff_format=h]
 in order to support large child node lists. So I suggest we stay with this for 
now and use the multi valued property if we need a stable order and/or 
orderability.

> There are JCR clients that depend on the ability to explicitly specify the 
> order of child nodes. That functionality is not included in the MicroKernel 
> tree model, so we need to implement it either in oak-core or oak-jcr using 
> something like an extra (hidden) {{oak:childOrder}} property that records the 
> specified ordering of child nodes. A multi-valued string property is probably 
> good enough for this.
