How can one tell that the parameter to the object tag is trying
to invoke an Active-X object ?  Is there some central registry
(not in the Microsoft sense of the word!) where such parameters
are enumerated and classified ?  If not, what is to prevent
a browser from applying its own (totally idiosyncratic) 
interpretation to the parameter and interpreting it as
anything that it chooses ?
