The Exclude MetadataFilter, identified by type="Exclude", filters out metadata for any entity or entity group listed inside the plugin's configuration.
The original name of this filter type prior to V3.2 was "Blacklist", support for which will be removed in a future release.
One attribute may be specified: matcher specifies an EntityMatcher plugin to use to identify the entities to exclude, allowing more flexible matching. Additional content will be included based on the type of plugin (see associated documentation)
Zero or more <Exclude> elements may be specified. Each elements content is matched against each entityID or group Name found in the source metadata and only matching entities are kept. When groups are excluded, all children of the group are excluded without further examination by any filters.
