The object is documented with XP version

It might not be documented, but I think it should be "recognized". That is,
using DiagramNode should not result in an error. Does it?

I am not familiar with the DiagramNode property.

But according to the Office 2010 help page "Object Model Changes Since ...
2003" in Excel VBA (search for DiagramNode), it is "hidden", not "changed"
or "removed".

"Hidden" means deprecated and not recommended for use. In contrast,
"changed" means the syntax has changed; and "removed" means it is no longer
available.
