When using "MDX Compatibility = 2" the children of the ragged
hierarchies are not retrieved when using the Children function.
Even in the MDX Sample Application when browsing through the hierarchy
these children are not shown.
These children members are only returned When using the descendants
function.

The Children function should return these as described in the
documentation (for MDX Compatibility = 2 )
Children = Returns all nonempty child positions and all children of
any empty positions in the hierarchy.
