I don't think that I do agree. The intention is primary. It may be that 
the authoring tool has to be 'pretty advanced', but it is as well to 
keep that in mind.
Otherwise one may design specs that users can't engage with. It is 
vital that technologies are bound by the needs of users, rather than 
their potential abilities.

There are web applications or tools that allow disabled users to create 
style sheets that suit their needs.
users are after all, in the best position to judge what their 
requirements are.
I am sure you are aware of the styling tools available on peepo.co.uk, 
which are designed for pre-literate users. (missing the cookie that 
would mean the result was less transient.)
IMO the user is creating the style sheet, I am not in a position to, 
not having any concept of who they are.
In a similar and not so different process the user could transform 
presentation to their satisfaction and in that process create a unique 
sXBL file.

It would of course be a better product if that same sXBL file could be 
used across a broad range of resources from different publishers.
(CSS style sheets provide some of this benefit for html)
However this will require extreme care and good will from developers as 
the range of resources and interactivity is so much the greater.

We fail the whole disabled community if we do not continuously ensure 
that our efforts take their needs into consideration.
good intentions are not enough.

Hi, Jonathan-

I don't think it's realistic for average users (much less people with
various accessibility issues) to create sXBL without a pretty advanced
authoring tool. I think that developers will have to create the 
which could be utilized by users. Do you agree with this?

Rather, may I suggest that there be included in the Spec explicit 
and mechanisms intended to facilitate this reuse? Something like:
"An authors of a document may indicate which sXBL components are the
defaults to be used with that document; these defaults may be 
overridden by
applicable user-indicated sXBL components that address that user's 
User-defined sXBL components may only be used for documents or document
fragments with the appropriate namespace."

It would be nice if a UA could discover compatible components; failing 
UAs should be able to access and apply components both locally to the 
computer and from libraries of components available on the Web.
