variable meta information (use with closing token)

If you want an array-variable (list of variables) to be displayed then you must use variable-token with closing tag. In addition you will need to know for each variable if it contains another array that must be formatted: the following temporary variables will help you doing so.

{mpf:var/key}	key name of current item in array
{mpf:var/val}	variable value of current item in array
{mpf:var/type}	variable type [array\|string]
{mpf:var/no}	position of current item in array
{mpf:var/depth}	level of current item in array (top level is 0)
{mpf:var/max}	number of items in array
