Interested in converting PDF to XPS

There is a tussle going on between Adobe and Microsoft about their respective formats, PDF and XPS respectively for final document formats that can be published and made available to large sections of users. A bit of background on why this is needed ?

What is PDF?
PDF stands for Portable Document Format. As the name implies, it is a data format that can be used to describe documents. Adobe, the developers of PDF, market software to create, edit and visualize PDF files. Because the specifications of the file format are publicly available, a lot of other companies develop software for PDF as well. In prepress, PDF is used more and more as a format to exchange data between applications.
Adobe Systems invented PDF technology in the early 1990s to smooth the process of moving text and graphics from publishers to printing-presses. At the time, expectations were modest, but no longer. PDF turned out to be the very essence of paper, brought to life in a computer. In creating PDF, Adobe had almost unwittingly invented nothing less than a bridge between the paper and computer worlds. Adobe's business -- and yours -- will never be the same again.

XML Paper Specification (XPS)
The XML Paper Specification (XPS) makes modern documents possible for all. Simply put, XPS describes electronic paper in a way that can be read by hardware, read by software, and read by humans. With XPS, documents print better, can be shared easier, be archived with confidence, and are more secure.
Microsoft has integrated XPS-based technologies into the 2007 Microsoft Office system and the Microsoft Windows Vista operating system, but XPS itself is platform independent, openly published, and available royalty-free. Microsoft is using XPS to bring additional document value to its customers, its partners, and the computing industry.

What can this particular converter, PDF to Vector Converter do (refer link) ?

PDF to XPS Converter (PDF2XPS) can be used to batch convert from Acrobat PDF files to other scalable vector graphics formats, such as EMF, WMF, SVG, Postscript (PS), EPS, SWF (Flash), XPS, HPGL, PCL etc. The software can be run using the handy interface or in batch mode to convert large volumes of PDF files in real-time. PDF to Vector Converter is available via an easily integrated COM object (or DLL Library, or Command Line), enabling developers to access the converter via any programming or scripting languages, such as Visual Basic, C/C++, Delphi, ASP, PHP, C#, .NET, etc. Using the COM object (or DLL Library, or Command Line), file conversions can be done consecutively or simultaneously.
