All the Silverlight techniques that I know of ready for porting have
been moved to the Editors' Draft of WCAG 2 Techniques,
http://www.w3.org/WAI/GL/WCAG20-TECHS/. I anticipate various issues with
them due to errors on my part, and minor differences between the
structure in the wiki and the structure we've been using for the other
technologies. I enhanced our structure a bit to meet what I saw in the
wiki but could have introduced various subtle errors, even into
techniques we haven't touched.

Here are some questions it would be helpful for you to think of as you
review these. I expect different people will look at different levels of
detail, but I'm hoping we can get review of all these issues from at
least somebody. For reference, the set of techniques by number and the
wiki page I ported them from is included at the bottom of this message.

    * Are there typographical or formatting errors?
    * Is there missing content?
    * Are heading levels correct, in the single-page, by-technology, and
      complete views?
    * Are the references to success criteria correct?
    * Are references to related techniques correct?
    * Are there broken links?
    * Are there broken images?
    * Is the alt text of images appropriate?
    * Do any images require extended descriptions? If so, what should
      the description be?
    * Most of the techniques in the wiki had test files / sample files
      at the bottom. In our other technologies, we've been putting links
      to such files at the bottom of an example, not at the bottom of
      the technique as a whole. Is the location of the references to
      such files appropriate for each technique?
    * References to test / example files are usually in the form of
      "...working example of XYZ". Is the verbiage I pulled out of the
      air for "XYZ" in these links ok? Note it needs to be fairly
      distinct, not something like "this example", because of the need
      to have unambiguous link text in views that have all the
      techniques together.
    * Do all the test / example files work? I modified some of them
      slightly to fit into a standard approach.
    * Is there / should there be downloadable source code for the test /
      example files? This is what we did for Flash.
    * Are code samples appropriately formatted? I took them unchanged
      from the wiki and didn't run any "pretty print" process on them.
      What would be most useful here is a complete reformatted version,
      rather than instructions on what needs doing, which is VERY
      painstaking to implement.
    * Are test procedures self-consistent and correct? I tweaked them a
      bit for consistency with our other techniques.
    * Some techniques (SL5, SL13, SL18, SL30, SL33) have more than one
      test procedure. Does the implementation of this work?

There are a few things I haven't yet done, in case you notice going through:

    * Techniques have pointers to the success criteria / Understanding
      document, but I haven't added pointers in the Understanding to the
      new techniques yet. This will need separate review when it's done.
    * There is diff markup that hasn't been cleared out yet, because I'm
      a bit nervous of the tool that does this... This won't be seen in
      the Silverlight techniques, though, because they're all new.
    * Language-specific terms just have generic emphasis, rather than
      more appropriate markup / formatting.
    * Advisory techniques are indicated as such in the XML but this
      doesn't yet show up in the HTML.
