This is ISSUE-15: Native browser-based WebID-only certificate display

(the name could do with improvement)

If all WebId enabled certificates that were self signed used the same DN then one could
use the build in certificate selection mechanism of TLS

This was brought up here initially by Bruno Harbulot:

It would require us to come up with such a DN, and for all WebID generated certificates to place those
in the Certificates.

There is an issue of how this would be compatible with CA issued certs with WebIDs too. There we should perhaps recommend a TLS protocol improvement.
