I'm doing SL#17

 

The working example doesn't seem to behave as expected. Maybe I'm missing
something, but as soon as the "Display Transcript button" is activated, the
controls disappear and text across the top says "The following text..." but
there does not appear to be any text transcript... and the only way to bring
back the controls is to reload the page.

TranscriptTextTestPage.html

 

Maybe someone else wants to look at it...

PS that's the end of my 3 but I think I will go through and check some more
test files. That seems to be the tough part...

I'm all for "downloadable code samples" for any working model examples.

The working example for that technique is actually missing some files
(images), so I am surprised you are seeing anything? I already reported that
issue to Michael.

 

You know, what might be happening is that my choice of the Ctrl+ (plus) key
is actually intersecting a browser-reserved key combo that I hadn't seen on
IE 8, that makes the whole browser zoom as a non Silverlight behavior. I
will test this tomorrow with the browsers you mention.

 

(I hadn't been testing with IE9 because the prerelease versions broke my
Windows-Eyes install.)

I just did a review of SL15.

*	SL15:
http://trace.wisc.edu/wcag_wiki/index.php?title=Providing_Keyboard_Shortcuts
_that_Work_Across_the_Entire_Silverlight_Application

The text seems fine, given that the target audience are SilverLight
programmers... no typos etc... I cannot evaluate SilverLight code.

 

However, I downloaded the test that was on the Wiki, and although the
application did zoom in and out as described, it did this on hover, as well
as on mouse click and keyboard CTL+ and CTL-.  And this behaviour was
unexpected. 

 

Same results in both IE 9 and Firefox 3.6,..

 

I checked it on our draft for porting and the application only seems to
display the instructions at the top of the page.

http://www.w3.org/WAI/GL/WCAG20-TECHS/SL15.html

The test is here:

Thank you, Michael. This is an enormous editing task.

I'd like WG members to sign up to review different techniques, so we get
complete coverage. We should review all the Silverlight technique in the
next 2 weeks, so we'll be ready for more reviews when the PDF techniques are
ported.

Please pick 3 techniques to review. I have set up a sign-up page at
http://www.w3.org/WAI/GL/wiki/Reviews; please put your name on the items you
are reviewing, so we don't duplicate effort. If you will not be able to
review techniques in the next few weeks, please let me know.

Loretta

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.
