Suggested change to Guideline 1.7 - Provide style sheets configuration

We were discussing Guideline 1.7 (Provide style sheets configuration) during today's call, and it occurred to me that we should be explicit that the user should be able to select any number of author- or user-provided style sheets to be applied to the current page, all pages on the current site, or all pages viewed in the browser.

Here's the proposal we worked out on the call:

    Summary: The user can choose which if any author-supplied (1.7.1) and user-supplied (1.7.2) style sheets to use.

    1.7.1 Author Style Sheets: The user can turn off the use of author style sheets, and for every author style sheet defined the user can choose whether or not it should be applied to (a) the current page, or (b) all pages for which it is defined.

    1.7.2 User Style Sheets: The user can turn off the use of user style sheets, and for every user style sheet defined the user can choose whether or not it should be applied to (a) the current page, or (b) all pages on the current web site, or (c) all pages.


We decided that we don't need to address where in the cascade these come because the CSS spec already ensures that user styles with !important take ultimate precedence.
