Decisions: DTD, XSD, RNG
- There 3 formats for XML grammars: DTD, XSD, & RNG
- All JATS tag sets are available in DTD, XSD, & RNG format
- The information content of each is equivalent
- Use the most convenient at the moment
- Switch among them if convenient
- If a tool you want to use prefers one format, use it. At least while using that tool.
- This is unimportant. Do NOT spend time or energy on this.
