[CWB] Empty XML tags not showing in CQP

[Javier Pueyo]

Thanks Andrew!

I will do as you suggest, Just to be sure that I have understand the trick:
I am supposed to enclose some material, probably the following word,
between my "empty" tags, and then create a visualization only for the start
tag, right?

regards,

Javier
