Schema and model references

Status:
• In Part 6 we reference several schemas and excel files  see below
o For schemas there are always two references:
a) “associated with this version” and b) the most recent schema.
o For CSV files there is only a single reference
• A similar issue exists with companion specs (like DI or ADI).

Questions:
• Do we need two different references to schemas (also questioned by IEC)?
o Alternative: reference a single schema file which we will update / fix if necessary. Include version information into the referenced file (e.g. v1.02.12, …).
 Text: “The most recent … Schema associated with this version …”
• Why do we not reference the UA Nodeset?
