I don't understand. Do you mean we should say something like 

6.3 Allow the author to transform HTML p elements into list elements, and
smil switch elements into excl elements

or that we should give examples like that?

There are a number of examples that would be useful (this is only a P3), such
as the ability to turn: 
+ HTML table-based layout into CSS
+ HTML paragraphs to lists and back
+ HTML br to p
+ SMIL switch to excl
+ SMIL switch to par
+ HTML (deprecated) FONT into heuristically determined structure
+ Word processor styles to web styles
+ lists of lists to tables and back
+ removing a container element from a collection of elements
+ adding a container element to a collection of elements
+ SVG g elements to symbol (with the associated requirement for defs and use
+ MathML presentational markup to semantic markup (or vice versa)
+ HTML deprecated presentational markup into CSS
+ invalid markup to valid markup (subject to user override as per 6.4
+ SPAN into RUBY

I would suggest that most of these should be incorporated into the
techniques, although a couple of simple concrete examples might be useful in
the checkpoint text.

To a certain extent this is a specialisation of 1.6 Allow the author to edit
the structure. However I think this is offering a functionality beyond the
requirement, and at a lower priority it is giving useful guidance as to what
would improve the function of the tool. In fact this is provided to some
extent in tools already - Word Processors, Netscape Composer, Amaya, are all
tools I have used in this way, and I would be surprised if they are the only

  Pick a concrete type (or two) of transformation and reduce the
  scope of the checkpoint to that.

  Then reduce the scope of the checkpoint to those. And add other
  checkpoints for other types. But "transformations" alone doesn't tell
  me what I should do.
