No, there isn't. I'm sure you wouldn't want someone taking your class, and
changing it.
What you can do is inherit from this class, and apply the attribute to the
inherited class. Of course now you have to deal with this new class instead
of SPUser.

I want to apply an attribute (ExpandableObjectConverter) to an existing
.NET class (actually, I want to apply it to
Microsoft.SharePoint.SPUser) Since this class already exists, I can't
just tack the attribue onto the class declaration. Is there any way to
do this?
