Called by Lightstreamer Kernel through the Remote Server to ask for the allowance of a publishing Mode for an Item (for at least one User). The Metadata Adapter should ensure that conflicting Modes are not both allowed for the same Item. The conflicting Modes are MERGE, DISTINCT and COMMAND.

Function ModeMayBeAllowed(item As string, mode As Mode) As bool
