MoveWithDescendants Element (XMLA)
Indicates whether the descendants of attribute members are also updated by the parent Update command.
The MoveWithDescendants element determines whether the Update command should not just update the attribute members identified by the Attributes element, but also that the descendants of those attribute members are to be updated as well.
This element applies only to attribute members in parent-child hierarchies.
For more information about updating members, see Inserting, Updating, and Dropping Members (XMLA).
