Commas that mean Or

There are two general varieties of comma-separated Events that appear in clinical trials criteria documents: (1) example lists, and (2) implicit Or lists.
How best to handle these?
- If a single category followed by examples - use Example Of for each, linking to the initial anchor Event.
- If multiple criteria, implicitly or'd - only use Or between criteria if the span between is "or" or "and/or". In other words, only annotate if "or" is explicit.
Why not annotate commas as Or? For one, it gets messy and unreadable quite quickly. Also, the patterns of implicit Or's are consistent enough that generally their logical normalization can be handled in post-processing.
