[CWB] reserved words in CWB

[Ruprecht von Waldenfels]

Hi,

in my setup, I unfortunately use the word "by" as the name of an 
attribute (similar to "word", "lemma", etc.). Unfortunately, if I make a 
query
[lemma="xwz" & by contains "ysd"]
I get an error message, because by is a reserved word.

The use of "by" (it stands for "Belarusian")  follows automatically from 
the architecture of my corpus, and I would have to change it in a lot of 
places. Is there any way I can continue using it by escaping it somehow?

Best,
Ruprecht
