     * # Decorators and model attribute management
     *
     * There is an optional argument to this command that applies or removes model
     * {@glink framework/architecture/editing-engine#text-attributes text attributes} brought by
     * {@link module:link/utils/manualdecorator~ManualDecorator manual link decorators}.
     *
     * Text attribute names in the model correspond to the entries in the {@link module:link/linkconfig~LinkConfig#decorators
     * configuration}.
     * For every decorator configured, a model text attribute exists with the "link" prefix. For example, a `'linkMyDecorator'` attribute
     * corresponds to `'myDecorator'` in the configuration.
     *
     * To learn more about link decorators, check out the {@link module:link/linkconfig~LinkConfig#decorators `config.link.decorators`}
     * documentation.
     *
     * Here is how to manage decorator attributes with the link command:
     *
     * ```ts
     * const linkCommand = editor.commands.get( 'link' );
     *
     * // Adding a new decorator attribute.
     * linkCommand.execute( 'http://example.com', {
     * 	linkIsExternal: true
     * } );
     *
     * // Removing a decorator attribute from the selection.
     * linkCommand.execute( 'http://example.com', {
     * 	linkIsExternal: false
     * } );
     *
     * // Adding multiple decorator attributes at the same time.
     * linkCommand.execute( 'http://example.com', {
     * 	linkIsExternal: true,
     * 	linkIsDownloadable: true,
     * } );
     *
     * // Removing and adding decorator attributes at the same time.
     * linkCommand.execute( 'http://example.com', {
     * 	linkIsExternal: false,
     * 	linkFoo: true,
     * 	linkIsDownloadable: false,
     * } );
     * ```
     *
     * **Note**: If the decorator attribute name is not specified, its state remains untouched.
     *
     * **Note**: {@link module:link/unlinkcommand~UnlinkCommand#execute `UnlinkCommand#execute()`} removes all
     * decorator attributes.
     *
     * @fires execute
     * @param href Link destination.
     * @param manualDecoratorIds The information about manual decorator attributes to be applied or removed upon execution.
