Indication of Language in a Multilingual Dialogue

The language code follows the standard of the so-called ISO-language-codes:
http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt

Symbol	<*tXX> with XX standing for the following variables
	EN	=	English
	DE	=	German (in non-German dialogues or multilingual dialogues)
	FR	=	French
	IT	=	Italian
	ES	=	Spanish
	JA	=	Japanese
		etc.

In a multilingual dialogue a language code is placed after each turn name according to the language used:

w001_ptd_001_AAA: <*tEN> good morning , ~John . how are you ?

w001_ptd_002_AAB: <*tDE> guten Tag , Herr ~Miller . danke , es
geht mir gut .

<*tXX> is followed and preceded by a blank space. Note that the transliteration of the dialogue follows the orthography of the respective language used.
