Remarks
If a function with this signature returns true for a given external content type, that external content type will be shown in the EntityPicker. If the function returns False, the corresponding external content type will not be shown in the EntityPicker. Multiple Validator functions can be used with a single BdcAccessor, in which case all Validator functions must return true for a given external content type in order for that external content type to be shown in the EntityPicker.
