As you can see on their page, Sublime Xaml has a lot of missing files to be called a library for Windows Phone.
Going deeper in the contents of the files you can easily read xml header
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
Investigating a little will bring you to understand that this repository is for iOS only, I can't say if it works since i'm not an iOS developer.
But to answer your question:
No this library doesn't work in your Windows Phone Project neither in a Windows 8 Project or something .NET
