I am assuming you would be the best person to answer this question, yet 
I am posing it to all. Is this statement from a SitePoint article 
accurate. If so should all of the sites I am developing and have 
developed with XHTML have the XMl declaration removed?
What are the ramifications of removing the declaration pending the 
possible use of a future XML workflow?

> <meta http-equiv="Content-Type"
>   content="text/html; charset=iso-8859-1" />
