Re: Spacing SC

I think that the LVTF should support SC's for spacing and font-family even
if we cannot come up with an example of HTML that does not allow a
JavaScript modification.

The reason is this. This level of support should have been part of 1.3.1.
It wasn't because WCAG WG used an intersection model. if a necessary
accommodation was not supported by all technologies, we could not make an
SC blocking certain authoring techniques.

Our language lets the author off the hook on a platform or in a file
language that can't support the change. This is a union model. If there is
one user agent that supports the feature then authors must write design
their page so that it does not conflict with that support. We can even say
one commonly used agent.

This model means that we should combine our techniques into one, so that a
person can get feature x only on browser A but needs to go to browser B for
feature y.

I think we need a group statement on this.
