Backward compability! Backward compability!! Backward compability!!!

The "Then it changed to ..." sounds very much like a bug. When did this change and was it reported back then? However, it should probably allow both ways with [[Subproperty of::Property:Superproperty]] as the preferred method. Either way its worth a bug report.

If there is an issue, I wonder why [0] [[Subproperty of::Area]] in Property:Surface area works. Locally I could not find any irregularities with either setting (with or without namespace).

I have to investigate.

Ah, good to know that both syntax variants work. Personally more in favour of additionally providing the namespace.
