OpenSpace Considerations
When appending OpenSpace layers, the following rules apply:
1) If the source layer has a column with a formula that differs from the formula of
the same column in the target layer, the target layer's formula overwrites the
source's layer's formula and is automatically applied to the entire layer.
2) If the target layer is schema 310-330, its classification overwrites the source
layer's classification(s). If the target layer is schema 400+, all classifications are
preserved in both the target layer and source layer. The target layer's active and
default classifications are adopted in the resulting layer.
3) If the source layer and target layer have identically named Extended Attribute
