Basically each servlet (but not the script) is registered via its own
{{ServletResourceProvider}}. The service.ranking is inherited from the
underlying servlet service (compare with

> URL: https://issues.apache.org/jira/browse/SLING-8182
> Project: Sling
> Issue Type: Improvement
> Components: Documentation
> Reporter: Konrad Windszus
> Priority: Major
>
> The documentation at
> https://sling.apache.org/documentation/the-sling-engine/servlets.html#servlet-registration
> should include a paragraph about the order in which potential matching
> servlets/scripts are considered.
> Aspects to be covered:
> * Consideration of property {{service.ranking}}
> * Amount of matching selectors and extension
> * Location of the matching resource type in the inheritance tree
> * OptingServlet vs. regular servlet
