Hi there,

So this action was to rewrite 1.11.2. We removed 1.11.1 because the 
viewport aspects are handled in 1.8 - however looking at 1.11.2 it seems 
to me 'link title' is not extended information - in fact it seems to me 
more basic than viewport handling. In this case I propose we reinstate 
1.11.1 as

1.11.1 (former 3.13.1) Basic Link Information:

The following information is provided for each link (Level A) :

     * link element content,
     * link title
     * link status (visited/selected/hover)

The Intent for 1.11.1 actually relates to 1.11.2 but can be modified 
easily as follows:

     * Intent of Success Criterion 1.11.1 (former 3.13.1):
             o     Users who use screen readers need to be able to 
easily discover information about a link, including the title of the 
link in the event that the link content has the same text as other links 
on the page. Otherwise the effect of selecting that link is not 
distinguishable.
     * Examples of Success Criterion 1.11.1 (former 3.13.1):
           o Robert, who uses a screen reader, hears a list of links 
read out saying 'more', 'more', 'more'. The browser also displays the 
link title so that Robert can distinguish which link he must select.
     * Related Resources for Success Criterion 1.11.1 (former 3.13.1):

Now I propose that we rewrite 1.11.2 to be:


1.11.2 (former 3.13.2) Extended Link Information:

The following information is provided for each link which does not point 
to an (x)html file (Level AAA) :

     * what will be the consequences of selecting the link (will a file 
download to desktop occur? Will a text file be opened by the browser?)
     * technology type (of the linked Web resource)
     * technology file size (of the linked Web resource)
     * predicted time to load (of the linked Web resource)
     * intra-page/onsite/offsite (whether the link is internal to the 
resource e.g., the link is to a target in the same Web page)



     * Intent of Success Criterion 1.11.2 (former 3.13.2):
             o Here we wish to mitigate the possibility of unexpected 
consequences occurring on link selection; this is especially the case 
for users who cannot see the visual cues present on the web page. For 
instance, visual styling can be used to imbue groups of simple links 
with semantic differences such as downloads or offsite links. This may 
then become a problem because links which seem the same to a user of 
assistive technology may have unexpected consequences when selected.

     * Examples of Success Criterion 1.11.2 (former 3.13.2):
           o Robert, who uses a screen reader, selects a link which is 
surrounding an image, the user agent downloads the image and displays 
the raw image file, Robert's assistive technology cannot describe the 
image or even say what has downloaded because raw images do not have alt 
elements and image downloaded and displayed is not an html file. If the 
user agent tells Robert that an image file download will occur on link 
selection he would not have made that choice as he cannot see the image.
