It has a modular design that makes it extensible through plugins. This is the media-streaming component of linphone, a GPL SIP video phone.
XSD is a W3C XML Schema to C++ translator. Provided with an XML instance specification (XML Schema), it generates C++ classes that represent the given vocabulary as well as parsing and serialization code. You can then access the data stored in XML using types and functions that semantically correspond to your application domain rather than dealing with elements, attributes, and text in a direct representation of XML such as DOM or SAX. XSD features support for in-memory and stream-oriented processing models, comprehensive XML Schema feature coverage, easy integration, and more.

Your distributed application does not have to be written in Java to take advantage of BitEvolution.
