HUH???
The format has always been
/* PHP CODE HERE */
/* BODY HERE */
$body = <<<EOF
EOF;
I know somewhere in the 7X series it got a little hosed in the default 10 custom islands.
But we were always advised to use the format listed above.
Then with the current version they decided to add the above format as a example note in case something happens again.
I am not aware that they circumvented using the Heredoc(EOF) method.
