IEBLP model has a deficiency that security level of object is changeless in the whole life cycle.The TBLP with time limited element is proposed to solve the deficiency.Time limited element is added into the security labels of subject and object,and its safety justices are improved.Finally,an Mandatory Access Control(MAC)model with TBLP for XML documents is realized by using XACML.
