I think I need a little help:
The usage of "string with blanks" will be really an improvement, but I
can't see the improvement of using an array of arrays for different
types of args when processing that (keep in mind that I'm not a php
guru, so please, maybe I only need a little help to understand)
In the argument parsing originated in PITS (and modified in the Cookbook
recipe GettingMarkupArguments) I can check if a arg is passed simply by
if (isset($arg['name'])) ...
or even better, if I provide defaults
$argdefaults['this'] = 0;
$args = GetDirectiveArgs($args,$argdefaults)
if ($args['this'] = 1) ...
How will this checks be implemented in ParseArg() ?
I'm also missing that default-stuff. Ok, I don't know what the
requirements for (:pagelist:) and (:searchlist:) are, but if I have to
use it for own markups, I can't see the advantages (right now).
I think the multiple occurence of a parameter in a call can't be solved
by any of both solutions.
