 Since MkDocs 1.4, plugins can choose to set a priority value for their events. Events with higher priority are called first. Events without a chosen priority get a default of 0. Events that have the same priority are ordered as they appear in the config.

 ### Handling Errors
 
 MkDocs defines four error types:
 
-#### `mkdocs.exceptions.MkDocsException`
+#### ::: mkdocs.exceptions.MkDocsException
 
-*   The base class which all MkDocs exceptions inherit from. This should
-    not be raised directly. One of the subclasses should be raised instead.
+#### ::: mkdocs.exceptions.ConfigurationError
 
-#### `mkdocs.exceptions.ConfigurationError`
+#### ::: mkdocs.exceptions.BuildError
 
-*   This error is raised by configuration validation when a validation error
-    is encountered. This error should be raised by any configuration options
-    defined in a plugin's [config_scheme].
