Re: Pointers - to point to content issues in the ShadowDOM / iframes

Hi, 

There was /deep/ (https://www.w3.org/TR/css-scoping-1/#deep-combinator) in CSS – which was designed to do the job, although now deprecated.  However, as a mechanism for our usage it might be useful – although we’d have to say in our docs that this is not a proper CSS locator – it is a pseudo locator.

All the best 

Alistair

    Hi Alistair,
    
    There is currently no group working on EARL. The Evaluation and Repair 
    Tools Working Group (ERT WG) was closed.
    
    Can you make a proposal for the "pseudo selector" and circulate it on 
    this list? If there is agreement in this group, then we can just write 
    it up somewhere and start using it. If it proves useful, then we could 
    look into standardizing this more formally. This could be an existing 
    W3C group, such as CSS, or another, depending on the how it gets used 
    within and beyond the accessibility community.
    
    Best,
