           Summary: Only one assembly can make use of the same xmlns
                    namespace

Example of issue

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en-US)
AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.151 Safari/534.16

In .NET multiple assemblies can have the XmlnsDefinitionAttribute assembly
attribute defined for the same namespace. The idea being that you can use the
same url in all of your XAML files and it'll magically find the right type
across all of the assemblies.

It looks like Mono's implementation only allows one assembly to use a
namespace. Attached is a repro.

Reproducible: Always

Steps to Reproduce:
1. Create two assemblies that specify the same XAML namespace, but map them to
different .NET namespaces.
2. Try to load xaml with the specified XAML namespace as the default namespace
in the file.
Actual Results:  
Duplicate key exception

Expected Results:  
All .net namespaces and types in marked assemblies to be mapped to the XAML
namespace.
