Namespace support is turned off by default:
By default, xmlns and xmlns:prefix attributes are reported
as regular attributes
Turn on namespace support by setting the http://xmlpull.org/v1/doc/features.html#process-namespaces feature to true
In this case, xmlns and xmlns:prefix attributes are not reported
unless http://xmlpull.org/v1/doc/features.html#report-namespace-prefixes is also set to true.
