By adding a "standard" binary XML format (be it based on ASN PER/BER or some other scheme) the interoperability gets bifurcated and the advantage of a single, auditable, interoperable format to be used in loosely-coupled environments disappears. In closely-coupled systems, you can use something else than XML (or a binary format). Since the coupling is closed, you do not need to follow a standard (although there are some reasons why you still may use XML). > > > also, I think lot of people are familar with security > > > loopholes in XML using processing instructions etc... what > > > kind of security loop holes need to be fixed?? > > > > There are no security loopholes in XML, only in the software that you > > use to process it. > > Is it not possible to specify some bad processing instructions?

The software needs to understand it to do anything with it. So if the software understands a dangerous PI, then you may have a security issue, if the software does not understand any PI, then you should not. > best, murali. > > > ----------------------------------------------------------------- > The xml-dev list is sponsored by XML.org <http://www.xml.org>, an > initiative of OASIS <http://www.oasis-open.org> > > The list archives are at http://lists.xml.org/archives/xml-dev/ > > To subscribe or unsubscribe from this list use the subscription > manager: <http://lists.xml.org/ob/adm.pl> >
