Hilmar,

I'd say it's a good design. You can simply type() test to see if the label exists and basically have direct access to the label via name without needing to search for it.

>I suggested my client to give the corresponding Labels in the "map" form meaningful names, like LblAAA and LblABC, to make it possible for a program to easily fill in the data, by just generating the Label name, checking if the Label exists (there may be invalid data), and fill in the "Power" value.
