XmlSerializer and consistent use of exceptions

hi,

in XmlPullParser we use XmlPullParserException to indicate API or
XML related exceptions that are different IOException that is used
to signal exception in underlying IO operations. however in XmlSerializer
we use only IOException and API or XML related exceptions may
be only reported by RunitmeException (with subclasses NPE and
IllegalArgumentException etc.) or IOException can be used to carry
all exceptions. i think that we should be consistent and also use
XmlPullParserException in XmlSerializer.

any opinions about it?

thanks,

alek
