ambiguous transformation rules

[kubaPod]

Perhaps a warning message should be generated when Solve finds more than one solution e.g.

"The provided transformation rule is ambiguous, only one of the possible transformations is applied".

See this question for more information.

Something like this will show up in newest release:

DChange::ambTrans: Transformation rule is ambiguous. The first of found solutions is used:
x->-(-(1/2))^(2/3) ([Eta]-[Xi])^(2/3)
y->([Eta]+[Xi])/3
Please add appropriate assumptions if this solution does not meet your expectations.

Any comments?
