.xsd file extension?

[kimkat_tkl]

A few years ago, I used a demo version of a pattern creator that allowed me to save the pattern. I have long since forgotten what the program was called and have deleted it from my computer. However I still have the pattern file. Does anyone know which pattern programs save their files as .xsd??

I think it is Pattern Maker for cross stitch.
