Bug#471211: [PATCH] support nil type extension

[Joey Hess]

Package: librpc-xml-perl
Version: 0.59-2
Severity: normal
Tags: patch

RPC-XML has the limitation that there is no support for the nil type,
which corresponds to perl's undef, python's None, and C's NULL. There is
an extension that defines this simple type, at
<http://ontosys.com/xml-rpc/extensions.php>

Many other RPC-XML libraries support this at least optionally. For
example, in python, there is an allow_none flag. The RPC-Xmlrpc_c perl
module (not packaged) supports nil. 

I needed it in RPC::XML, so I developed the attached patch. I took care
to not have it emit or parse "<nil/>" unless $RPC::XML::ALLOW_NIL is set
to 1.

Please consider applying this patch, and encoruaging upstream to do so
as well.
