[Inkscape-user] Transparent text or text mask.

Hello everybody!

Does anybody know how to use text as object-mask?

I need to cut a text in a picture so that the text would actually be transparent!

The goal is easily achieved converting text in path, and grouping it with a background, and then using it as a mask for the picture. But in this way I'm loosing the chance to change what is written in a second moment.

Reading some references, I saw that text objects should work as any other objects about masking, but they they don't.

What am I missing?
