In this chapter we discuss further security issues for XML. Note that there are two aspects: one is securing XML documents and the other is using XML to specify policies. We discuss both aspects. We give examples and show how access control rules can be enforced on XML documents. We also discuss security for XML schemas and security for name spaces. Then we discuss how policies can be expressed in XML. One of the advantages with a specification language such as XML is that one can specify rules in this language. However, since XML represents data, policies specified in XML can be enforced on data represented in XML.
