A new version of the XISF specification document (third public draft) is now available online:

https://github.com/PixInsight/XISF-specificationThis version is a significant step forward and, in my opinion, quite close to a final format specification.
Main changes:
- New TimePoint property type.
- Dropped the String8 and String16 property types. All text contents are now UTF-8 in XISF, so there is only a String type.
- New Reference core element.
- Formalization of a set of standard properties of astronomical images.
As always, thanks to the people who are helping me with this project.
