[1] it's not possible to create a dataset with an apostrophe in the dataset name (e.g. Eric's dataset)
[2] it's not possible to place a numeric digit (0-9) in a column name (e.g. tax_1)
[3] it's not possible to place an apostrophe in a column name
[4] it's not possible to place a space in a column name (e.g. daily specials)
[5] it's not possible to place an apostrophe in data (e.g. Michael's special sandwich)
[6] columns can be assigned the same column order number
[7] when creating or editing a dataset, rows are numbered begin at 1, however when adding a dataset to a region, in Edit DataSet View, it seems row numbers begin at 0. (e.g. to display data from row 3 to 6, it's necessary to specify Lower Row Limit 2 and Upper Row Limit 5)
[8] specifying 0 in Lower Row Limit causes all rows to be displayed, regardless of the value in Upper Row Limit.
[9] it's not easy to determine which dataset from the library is associated with a dataset view in a region, once it's been placed into the region.
#6 is OK - all others are fixed.
