xml validation failure when an & is present...

[Phil Sullivan <pa...@rcn.com>]

Hello -

First off, congratulations - Forrest has helped me get a professional 
looking site up and running for my wife with  the only glitches being 
operator induced (that would be me)....so far i've figured them out 
using he doc's and examples - but this one has me stumped.

I am getting validation errors when I  include strings like this in an 
xml docs:

[F12]. [IRKBD:F12:P&R]


I've tried using <code> </code> as well as <source> </source> with no 
success. It appears the & is the problem since it builds fine without it 
and complains about whatever character follows it....

My knowledge of XML is *very* limited, mostly gleaned from the Forrest 
doc's and examples - so my apologies advance if I'm missing the obvious 
here, or if I'm asking in the wrong list.

I've appended the error and a snippet from the document.

Thanks!

Phil
