The Duke of Austria shall have authority to dispose freely of his lands, to give them or transfer them to whomever he will in the case, which God forbid, that he should die childless. And the Empire may not hinder him in this.
 Further, the aforesaid Duchy of Austria shall have each and every right, liberty, and guarantee known to be possessed by other Imperial principalities.
 We also desire that, when the circles and regions of this duchy are expanded through inheritances, gifts, purchases, acquisitions, or in any other way, the aforesaid rights, liberties, and guarantees shall be fully possessed by the additions to the aforementioned principality of Austria.
And so that this, Our Imperial mandate, shall remain legally in force and incontestable forever, We have had it prepared in writing and sealed with Our seal.* –
