In my experience you need to purchase the schema. You can go to http://x12.org to find out more. Depending on your usage and needs it can be a bit pricey for licensing especially if you only need one schema. If you have a partner that has access you could piggyback on there license assuming you have a working relationship with them. Unfortunately I did not see any option to purchase just a single schema, though there was something like that in the past as I have a colleague that did so. You can try to contact the org to inquire.
You can certainly do this. Of course that means you have to maintain it for versioning and such. I am also not sure on the legal licensing issues here if that is something that is a risk for you. After all it is the content of the file that is licensed, not the file itself.

Ah, thank you for the information. I just build my own in Notepad++.

Best of luck with X12!
