I think that prefixedattributes should simply disable the use of proc
modifier . The probability of having code that needs both is almost zero,
the  syntax is very old and almost not used.
Mode Delphi(Unicode) enables prefixedattributes, all other modes need an
explicit modeswitch to enable it.
Let's keep it clear, simple and unambiguous.
