> RowSchema is essentially a container class for a list of fields.
> * it can be constructed from a "list"
> * the list can be set
> * the list can be accessed
> none of the above methods try to protect the data inside; hence the following
> could easily happen:
> {code}
> s=o1.getSchema();
> col=s.getCol("favourite")
> col.setInternalName("asd"); // will modify o1 schema
> newSchema.add(col);
> o2.setSchema(newSchema);
> o2.getSchema().get("asd").setInternalName("xxx"); // will modify o1 and o2
> schema
> [...]
> {code}
> not sure how much of this is actually cruical; exploratory testrun revealed
> some cases
