I've put some text inside a rectangle using inkscape so the tree is like
<svg:rect><svg:text><svg:tspan>text....
The problem is, I can't see the text. I've tried fiddling with the opacity of the rect to no avail. There should be a way of doing this from the UI?
Edit

I'd expect to be able to see this in inkscape.
The workaround is to put text on a layer above the box (the intent is that the box obscures the layers below it) and not try and get clever with nested tags. Shame it doesn't work though.
