There is usually a way to make things up where metadata is concerned. There is often a fair amount of flexibility in the way metadata is interpreted, and history tells us this has happened already. 

Is there something in this proposal that makes it more prone to mis-use do you think?

If a resource had no specific accessibility feature, yet was nonetheless accessible to someone, how would it be classified? As Chaals notes, a search for a resource with text descriptions for images would exclude any resource that consisted only of text, yet such resources would likely be accessible to a person requiring text descriptions for images.

Speaking as someone involved in the standards effort, and someone (like many others) who has a disability, this feels like a very binary assessment to me.

The two communities can (and sometimes do) collaborate. User research is another way the standards community can seek input from different disability communities, and open reviews of proposed ideas (like this thread) are yet another way to bring people from outside the standards effort into the conversation.

Of course these things aren't perfect solutions, but few things are. If we start from an "either or" position, I suspect we'll set ourselves up for failure before we start though.

The notion of "real people" makes me smile, but I take your meaning.

The proposal seems to be about making it possible to search for resources that a person with a disability can use. It feels like something of a jump to go from there to "personalisation and customisation", not least because storing and maintaining a profile starts privacy alarm bells ringing in the back of my head. That's probably a conversation for another time and place though.

To the question of mis-use, I'm still struggling to understand how this proposal is any more open to abuse than any other metadata model (Schema or otherwise)?

Léonie.
