Public User Defined Types

[TheVader]

I'm trying to use a public User Defined Type from within a class module. The UDT has been declared in a public module, the instance in a class module, like this:

'Module:
Public Type tText
    Font As String
    Format As String
End Type
 
'Class Module
Public Text as tText

This is not allowed, apparently. The compiler gives me this error:

Constants, fixed-length strings, arrays, user-defined types and Declare statements not allowed as Public members of object modules.

Why can't UDT's be used publicly?
