Action-730 Revise GL 1.7, pay attention to current behavior and
aspirational subpoints, adjust  IER and add where necessary

No IER included, just SC.

-----------

we adjusted the wording of 1.7.1 during the telecon on 17May2012 -
included in this message.

no changes made

1.7.1 Support User Stylesheets:
If the user agent supports a mechanism for authors to supply
stylesheets, the user agent also

provides a mechanism for users to supply stylesheets.

------
The other SC present current SC, current UA behavior, proposed rewrites.

current 1.7.2 Apply User Stylesheets:

The user can turn on the use of user (Level A)

    (a) the current page, or
    (b) all pages on specified web sites, or
    (c) all pages.

current UA behavior for 1.7.2:
IE, Opera: user can apply personal stylesheets for the entire UA (all
top level viewports). -- c)

ALL pages
FF, chrome: need an extension (stylish, etc) -- b) all pages on
specified website
no known browser or extension allows a) the current page

Proposed rewrite:
eliminate a) the current page, do not write an AAA SC for this function.

1.7.2 Apply User Stylesheets:

The user can turn on the use of user stylesheets (Level A)

    (a) all pages on specified web sites, or
    (b) all pages.

-------
1.7.3 Author Style Sheets:
The user can turn off the use of author (Level A)

    (a) the current page, or
    (b) all pages for which it is defined.

current UA behavior for 1.7.3:
IE , FF,  Opera: user can turn off author stylesheets on a per page basis
Chrome: needs the developer extension to disable author style sheet
FF and Chrome: the developer extension allows selecting author
stylesheets on per page

basis.

proposed rewrite: eliminate b)  all pages for which it is defined.

1.7.3 Author Style Sheets:
The user can turn off the use of author stylesheet on the current page (Level A)

---------------

1.7.4 Save copies of stylesheets:

The user can save copies of the stylesheets referenced by the current
page, so that they can

edit and load them as user (Level AA)

current UA behavior for SC 1.7.4
FF & chrome - developer toolbar extension, user can edit/save author css
IE, opera - no ability for user to save CSS from the UI. must view
page source, find css link, paste in address bar, save results.

Proposed: move to AAA. no current functionality. Only some browser can
do this with an extension.


-----
the intent for 1.7.1-3 needs some work. the example presents a
scenario that is not covered by the current SC. The IER or 1.7.4 will
be created.

propose: Update the REsources for 1.7.1-3 as follows.
