I realized that was sufficient to your task but not complete if you wanted to trim leading and trailing white-space of the entire element, as I do in my XSL training material. Below I use all of the template rules from my development environment.
I've edited your description with leading and trailing space, then illustrated the trimming by adding bangs before and after the description.
I hope this helps.

That's not exactly "weird", it is doing exactly what you asked for (but it isn't what you want).
How about preserving the existence of leading and trailing white-space by wrapping the node before normalization and unwrapping it after?
