+parser and should be used when there is a need to process quickly and
+efficiently all input elements (for example in SOAP processors). This
+package is a stable XmlPull parsing engine that is based on ideas from XPP
+and in particular XPP2 but completely revised and rewritten to take the best
+advantage of JIT JVMs.
+
+MXParser is a fork of xpp3_min 1.1.7 containing only the parser with merged
+changes of the Plexus fork. It is an implementation of the XMLPULL V1 API
+(parser only).")
