it works

When got some OXPS files(I know that they are Microsoft Windows 8 reader openxps document file) on my Mactonish, it cant determine which program to open them. Known this XPS viewer from a mac forum and got it, it works and open the OXPS document well for me, conversion and bookmark features seems all are OK too.
