Comment: mention SeamlessAccess, update URL for embedded SWITCHwayf


The user is generally sent directly to the DS in a redirect, but more modern DS implementations (e.g. SWITCH's WAYF, the Embedded Discovery Service  or CESNET's wayf) also allow an application to directly embed a discovery interface into a page. The interface can be customized by that page.


The central DS is usually operated by a federation. This creates problems for applications that serve multiple federations. As the prospects for a global discovery service appear limited for both user interface and practical reasons, this drawback is likely to linger.
A central DS not operated by one federation, that also allows for integration methods with a user experience similar to a DS "run with the resource", is SeamlessAccess.
