Ah, I was not aware of this behaviour!

Let me confirm, that I should specify "proxyattrset 0 1.1" to match  
an empty attribute list, and only an empty attribute list.  Will a  
'*' than match emptiness as well, or does it only match where there  
is some attribute specified by the client?

I will work on this as soon as I am able to, although it seems this  
won't be for a couple of weeks.  I will be in touch.  Thanks again  
for your work and for your very timely response.
