ModifyGroupRequest Element
Modifies a group account by sending a request to a conference center.
The OptionList element must only contain a groupID (of the StringOption element) specifying the new group ID of the group being modified. The size of the groupID value is between 1 and 64 characters in length.
Nesting groups within groups is no longer supported. However, the OptionList element can be used to rename a group.
