?Object is ANY
this is an idea of Otto to defeat acedb strong typing
myself I object to using ANY except at kernel level
if i had been able to do it, i would have make it disapper^Har from
the user interface, but at the beginning, i could not separate the
needs of the kernel (which does require ANY) from the user interface
techniclly:
-?Collection is UNIQUE ?Object XREF is
means that in a given collection there may be one or zero
Object after the tag is
and that the Collection is pointed back automatically (xrefed) in Object
