.XOML File Extension

What is a XOML file?
File written in XAML (Extensible Application Markup Language), a descriptive programming language used for creating user interfaces; contains a tree-based structure that defines a root workflow node and nested sub-elements; may also contain embedded segments of code.
NOTE: Windows Workflow Foundation (WF), the creators of the ".xoml" file extension, originally used a syntax different than XAML. However, they later adopted the XAML syntax used by the Windows Presentation Foundation (WPF). Therefore, the .XAML extension is often used instead of ".xoml." The ".xoml" extension remains for historical purposes.
