DeleteWithDescendants Element (XMLA)
Indicates whether the descendants of attribute members are also deleted by the parent Drop command.
The DeleteWithDescendants element determines whether the Drop command should delete the attribute members identified by the Where element, but also that the descendants of those attribute members are to be dropped as well.
This element applies only to attribute members in parent-child hierarchies.
For more information about deleting and updating attribute members, see Inserting, Updating, and Dropping Members (XMLA).
