Notes: For FOLDERCREATE requests or non-email collections, the parent
seems to be set to the root of that collection type and the EAS type is
included. For new root email folders, the parent is set to ROOT.
For FOLDERCHANGE requests, the type is NOT included so the backend must
be able to determine the folder type given the folder's id only. Also,
the parent element does not seem to be transmitted by the clients I
have tested, so even though it is included when creating the new
folder, it is NOT included when edting that same folder. *sigh*
