Comments

When a key element is deleted using this function, all offspring of the key element (both key element children and non-key element children) and all their respective children are also deleted.

Below are illustrations of this:

For the sake of these illustrations, the order of siblings is top to bottom.

NOTE: The numbering of the items of interest is arbitrary, and does not imply order.

In this illustration item 2 will be deleted. If any of the children of item 2 had children, these would be deleted also.

In this illustration item 3 will be deleted. Again, if any of the children of item 2 had children, these would be deleted also.

NOTE: Key elements should not be deleted using LDicomDS::DeleteElement. Deleting a key element using LDicomDS::DeleteElement will not delete any child key elements, but will delete information that references the child key elements.
