JXTA and XML

XML is the basis for most of the protocol in JXTA

• Language portable
• Can be validated
• Evolving standard for portable data structures

The downside:

• Not compact
• Encryption largely bypasses any benefit of XML
• Poor support for binary

JXTA group has created a "simple" binary message transport. They have likewise used terse language and acronyms for tag names. XML in JXTA is really hard to read.
