Support this service to represent a group of hyperlinks.
The main interface XAccessibleHyperlink relies on the
interface XAccessibleAction for representing the actions
connected with each link. The interfaces give access to different kinds
of information describing the links.
The XAccessibleHyperlink references text that contais the
represented links. This is reflected by having a
AccessibleHypertext service that supports the
XAccessibleText interface owning and providing accessible
hyperlinks.
