Link additional binding uses (candidate, current, ui, starter, and component) to documentation that explains their meaning

[dbojicic]

In the Additional Bindings table, the purpose where the binding is required, extensible or preferred have links to the binding strength section of the FHIR standard. Max and min bindings also have resolving links.

However, the use of other additional bindings such as candidate, current, ui, starter and component is not explained in the IG, and there are no links to the documentation that explains their semantics (see a screenshot below, noting this was a test only). I am aware of issue #922, which proposes hyperlinking the "Additional Bindings" heading to the 'ElementDefinition-definitions.html' entry for additionalBindings, but I don't believe this offers a clear solution for this issue.

A specific change is requested to link these additional binding uses (candidate, current, ui, starter, and component) to documentation that explains their meaning and usage.
