informative due to variation across langauges

It used to be that one could describe informative properties saying, "some
properties are valid for most languages but not all and so are informative,
such as case mappings". Case mappings gave an easy example for why to have
informative properties. Now that the mappings are informative (with
normative exceptions listed in SpecialCasing.txt), it's harder to give an
easy explanation for why some properties are informative.

Can anyone think of other examples of informative properties that are so
because the property is typical but not true for all languages?

Can anyone give me a specific example of why Line Breaking or East Asian
Width properties aren't normative?
