VMDK Child disk creation help

Hi,

While creating a child disk is this sequence possible

1. Create a disk using VixDiskLib_Create(with parentpath specified in the appglobals) instead of VixDiskLib_CreateChild.

2. Use VixDiskLib_Attach to attach the created disk to a parent? (assume the created disk contains only the changed block data).

The VDDK documentation spcifies "Attaching an  arbitrary  child  in  a disk   chain". Can someone tell me is the above implementation valid - if not how can a arbitray child be added in a disk chain?

Any help is apperitiated.

Thanks,
