Re: NVDL v. XProc or XProc & NVDL?

Hi David,

I stopped development on oNVDL because I moved that into Jing itself, so 
if you get Jing then you will have NVDL support there.

Last year at XML Prague I presented an NVDL implementation in XSLT and 
orchestrated with an XProc script - the source for that was committed 
inside the oNVDL project.

If you need any information on the NVDL support in Jing or if you 
encounter any issues with that I will be happy to help.

Best Regards,
George
