Hi Jim,

As a published author I'm going to jump in here and make a correction 
you might think it small but it's extremely important.

Under WIPO and copyright law setout therein, facts ARE NOT 
copyrightable.  Powercom cannot dictate terms to us or to anyone on how 
the the documentation they sent to us is used.  Only expressions are 

I realize it may be hairsplitting to you.  Let me illustrate:

The sentence:

"The AC Adapter runs off 60Hz power"

is not copyrightable.  However, the sentence:

We recommend that the AC adapter be used on a power strip with surge 

is copyrightable because it's an expression.

In short, Powercom has no legal ability to exercise copyright control 
because of any business requirement to make information available - in 
short, they may want the old docs removed (so as to enhance sales of new 
devices or any other reason) however they have no legal authority to 
demand this.

Do not give them a legal power to do this by asking whether or not we 
can keep the old docs up.  Under copyright law they do not have this power.

That doesn't mean we shouldn't be nice, they asked us to remove the old 
docs, and while they have no legal authority to make that request we can 
acknowledge that they have expressed that desire and try to honor it as 
much as is reasonable by prominently marking the old docs as obsolete.  
I'll assume their motivation to take the old docs down is to prevent 
confusion among developers when there is a conflict between the old doc 
and the new doc.  I'm just trying to explain we can't do that since we 
have to still support the old gear, but we can eliminate that possible 
confusion by being explicit on what is what.
