+ * Helps find external documentables that are not provided by Dokka by default.
+ *
+ * By default, Dokka parses and makes available only documentables of the declarations found
+ * in the user project itself. Meaning, if the project's source code contains a `fun foo()`,
+ * it must be returned by [SourceToDocumentableTranslator]. However, if the user project
+ * depends on an external library which has a `fun bar()`, it will __not__ be available and
+ * documented out of the box.
+ *
+ * This provider helps you find documentables for the declarations that are present in
+ * [DokkaSourceSet.classpath] during runtime, but are not necessarily from the user project itself.
+ *
+ * For example, it can help you find a class that comes from a dependency, which can be useful
+ * if you want to get more information about a supertype of the project's class,
+ * because [DClass.supertypes] only provides the supertype's DRI, but not its full documentable.
+ *
+ * It is expected to work with all languages supported by the analysis implementation,
+ * meaning it should return Java classes if Java as an input language is supported.
+ *
+ * If you query DRIs of local project declarations (not external), it should generally work, although
+ * it's not guaranteed that the returned value will be 100% equal to that provided by Dokka by default.
+ *
+ * Note: because classpath entries consist of compiled code, the returned documentables may have some
+ * properties set to null or empty, because some information cannot be extracted from it in any way.
+ * One such example is KDocs, they are present in source code, but not in compiled classes.

+ * If the [dri] points to a non-class-like declaration (like a function),
