Hi there. You're named as the author of
org.xmlpull.v1.dom2_builder.DOM2XmlPullBuilder, so I thought you might be
interested in this. Basically, attempting to parse the following XML throws
a NullPointerException in declareNamespaces. The XMLPull spec says that
getNamespacePrefix(i) may be null if namespace i is the default, but you do
a .equals comparison on it in your inner loop.

Attempting to parse this XML should illustrate the problem (if it doesn't,
then I'm just making myself look stupid
