I know of a couple of publishers interested in the XML space that are
considering a book dedicated to the subject of XML and Security, e.g. XACML,
SAML, XKMS, XML Encryption, XMLDSig, DSML, general issues related to
security of XML initiatives and use, e.g. SOAP, ebXML etc.
If anyone is interested in authoring chapters in such a book, let me know.
