I still can't get that (or similar YAML) to produce the format 
needed by HTMLScrubber.

My YAML is:

     filter:
       - TrimEdges
       - type: HTMLScrubber
         allow:
           - 'p'
           - 'span'
           - 'strong'
           - 'em'
           - 'u'
           - 'li'
           - 'ul'
           - 'ol'
           - 'br'
         default: 0
         rules:
           - p:
               style: 0
               class: 1
               '*': 0
           - span:
               style: 1
               class: 1
               '*': 0
           - '*':
               '*': 0
         comment: 0
         script: 0

And I'm expecting a `rules` list like this (to match what 
HTMLScrubber expects):

@rules = (
     'p' => {
         'style' => 0,
         'class' => 1,
         '*' => 0
     },
     'span' => {
         'style' => 1,
         'class' => 1,
         '*' => 0
     },
     '*' => {
         '*' => 0
     }
);

But instead I'm getting a list of hashrefs:

@rules = (
     {
         'p' => {
             'style' => 0,
             'class' => 1,
             '*' => 0
         }
     },
     {
         'span' => {
             'style' => 1,
             'class' => 1,
             '*' => 0
         }
     },
     {
         '*' => {
            '*' => 0
         }
     }
);

So is it possible to write YAML that will generate a suitable 
(simple) list, or will I need to munge the `rules` list before 
passing it to HTMLScrubber?
