From Scott's page about filters post-processing filters transform
valid HTML to valid HTML. Since tags like <typo> and <amazon> aren't
valid HTML they don't fit that description. An earlier post talks a
little bit about why he made the dinstinctions he did.

From the second link I gave, "As long as the Typo macro tags fit into a
clean namespace and they don’t have side-effects when they aren’t used,
there’s no reason to ever turn them off. If a macro tag filter is
installed, then it should be used on all articles."

I haven't used it but the documentation for the amazon filter suggests
you use the form:
This is valid HTML (although somewhat nonsensical given the target of
the HREF) and the post-filter will turn it into other, valid, HTML.

FWIW, it sounds to me like you want a macro, too.
