Default value for enumeration isn't correctly computed with no package

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a .proto without a package line
2. Add an enum
3. Add a message using that enum as an optional member without default value 
explicitly defined.
4. Compile to .cs

What is the expected output? What do you see instead?

Expected the default value to show up as it is the case when there is a package 
defined but instead of "MyEnum.MY_MEMBER" got "MyEnum.".

What version of the product are you using? On what operating system?

"NET3" from "protobuf-net r282.zip" on Windows 7 x64. 

Please provide any additional information below.

Bug is in GetFirstEnumValue in csharp.xslt it search for 
"ancestor::FileDescriptorProto" but should instead search for 
"ancestor::FileDescriptorProto[package]"

For me it happens even when package is specified.

I have a lot of protogen/xslt maintenance coming up soon on the roadmap - will 
look at this then

Thanks in advance. Right now I result to generating and fixing C# files by 
hand. Would be nice if the process was fully automated.
BTW - maybe instead of "VS custom tool" there should be an MSBuild task?

I will investigate what that takes to integrate. The nice thing about custom 
tools is that the IDE takes care of them.
