[XeTeX] Slightly embarrassed.... why does \newfontfamily not do what I expect?

Hi Wilfred,

replace the \cjkfont command here with \setmainfont{Kozuka Mincho Pr6N} 
to explicitly set the document's main font first. You will use the 
\cjkfont command whenever you need to do switching, but its effect is 
scoped to the current block (when using intercharclasses this is 
irrelevant, since it'll be issued whenever it is needed but for the font 
to act "from that point on until the end of the document" use 
\setmainfont{Font Name}.
