Yes, and that's where I'm getting confused, because it says right there 
that:

     The control names/values are listed in the order they appear in the
     document. The name is separated from the value by `=' and name/value
     pairs are separated from each other by `&'.

*wink*

... but on the other hand, I see that there was a recommendation from the 
W3C that people should switch to semicolons:

Ok, I understand now.  This is really a problem with legacy cgi libraries 
more than anything else.  Recent versions of cgi-parsing libraries from 
other language communities (like Python and Perl) now handle semicolons 
and ampersands, so it's really the laggards that are causing a problem. 
I accept the current default state of current-alist-separator then; it 
makes sense.
