Yes.

<pre wrap="">Say that in my corpus I've collected information about the speakers, and some of them can speak more than one foreign language. I would like to have a structural attribute like
foreing_languages="ES|PT|IT"

<pre wrap="">
Simply encode them in feature set format as you would for positional attributes. In your case, you need to add leading and trailing "|" separators as specified in the tutorial, e.g.
<speaker foreign_languages="|ES|PT|IT|">
...
</speaker>
and declare the foreign_languages XML attribute to be set valued (cf. "cwb-encode -h"):
cwb-encode .... -S speaker:0+foreign_languages/
(the trailing slash marks foreign_languages as a set-valued attribute). cwb-encode will validate the set notation of attribute values and re-order the set elements alphabetically (keep in mind that sets are unordered, so you cannot specify first, second and third foreign language in this way).
You will then be able to restrict searches to speakers who know Portuguese e.g. with a global constraint such as
... query ... :: match.speaker_foreign_language contains "PT";
Hope this helps,
Stefan
