Support nested elements in @Key annotation

[GoogleCodeExporter]

The @Key("param") annotation does not support nested tags per Partial Response 
idioms.  For example: @Key("gf:symbol/@symbol") should return the symbol 
attribute from the symbol element within the element being parsed, without 
requiring the user to create a new class as an intermediary.  1.2.1-alpha fails 
to parse and returns null.  Support for nested elements would be of great help 
in parsing as some of the Google APIs nest rather deeply and it would be useful 
to be able to flatten the structure somewhat.  Another example is 
@Key("gf:positionData/gf:marketValue/gf:money/@amount" -- Does that really need 
three nested classes to parse?

I've gotten multiple features requests like this from other sources as well.  
Thanks for filing a formal feature request.  Good explanation of the benefits 
of such a feature.  It would make the XML data structure much easier to work 
with, e.g. not having to check for nulls for the intermediary classes.

Unfortunately, it would be a rather complicated feature to implement.  So 
although I agree it would make it easier to use, it has not yet been determined 
if the extra complexity in the implementation is worth the user benefit.
