Description
Returns and sets the flag indicating the preference for extending compatibility with pre-ArcInfo 8.1 releases at the cost of allowing improperly used IRelationalOperator comparisons to return meaningless false values.
If Pre81Compatibility = TRUE, meaningless comparisons of non-Clementini geometries using Clementini relational operators returns FALSE (even though no meaningful relation actual took place).
If Pre81Compatibility = FALSE, these comparisons will return an error message indicating that the attempted comparison is invalid and would not have returned meaningful results. By default, Pre81Compatibility = TRUE.
