new plugins and 3rd party javascripts

Hi,
who knows, what have to be attached to SVN, if a new plugin should be published ?
Does this also include complete 3rd party javascript libraries, that normaly comes from an other vendor ?
As example, if a WP admin center plugin depends on let’s say codepress.js library and the plugin uses and extend it, does it have to be a SVN trunk too or is it enough to have the download package containing a copy and ref to vendor at description of ?

thanks and interested about reponse.
