XML Database Perspective: The XML Database Perspective contains an explorer over the defined connections (you can define multiple connections at one time and browse them in parallel), a table component for data inspection/editing and the editor area.

SVN Client: The oXygen SVN Client is composed of several views allowing you to browse the Subversion repositories and your local working copies, compare and merge modifications, check the revision history. All the views are dockable. This means you can move them to create the optimal layout for your use case.

Editing Office Open XML files: oXygen offers a complete framework that provides support for editing and validating documents from the Office Open XML zipped package. The NVDL schema can be easily customized to allow user defined extension schemas for use in OOXML files.

XPath support: The XPath expressions can be quickly edited and executed using the XPath toolbar. The content completion support shows documentation for all the XPath 1.0 and 2.0 functions. The function signature tooltip presented above the current function indicates the names and types of the edited arguments.

FTP & WebDAV Support : oXygen supports remote editing, using the FTP/SFTP and WebDAV protocols. The remote files can be added to the project and can be subject to XSL and FO transformations.
