Why were special tags added? I don't see any need for anything above
the two concepts of 'replacements' and 'sections' that jonpy provides.

I think the three interesting concepts in jonpy are:

  * absolute minimum of non-html code in html templates

  * correspondence between html sections and nested classes, e.g.:

    HTML:
      <p>Top level.</p>
      <!--wt:section--><p>$$replacement$$</p><!--wt:/section-->
      <p>Top level.</p>
    Code:
      class main(wt.TemplateCode):
        class section(wt.TemplateCode):
	  def replacement(self):
	    return "Section."

  * dual file hierarchy for html and code, e.g.:

      DOCUMENT_ROOT/index.html
      DOCUMENT_ROOT/img.jpg
      DOCUMENT_ROOT/thing.html
      DOCUMENT_ROOT/subdir/index.html

      DOCUMENT_ROOT/wt/index.html.py
      DOCUMENT_ROOT/wt/thing.html.py
      DOCUMENT_ROOT/wt/subdir/index.html.py

Presumably bad things still happen if the designer deletes the tag
itself that the magic attributes are attached to though.

I'm not sure what you mean here. Can you give an example of what a
"validation package" might do?
