19.10.5:  (A minor note on interaction between ``lo'u ... le'u'' and ``zoi'': 
The text between ``lo'u'' and ``le'u'' should consist of Lojban words only. 
In fact, non-Lojban material in the form of a ``zoi'' quotation may also 
appear. However, if the word ``le'u'' is used either as the delimiting word 
for the ``zoi'' quotation, or within the quotation itself, the outer ``lo'u'' 
quotation will be prematurely terminated. Therefore, ``le'u'' should be 
avoided as the delimiting word in any ``zoi'' quotation.)

How would you lex the following?:
/laxidEkel.rIrxefa'otIgriselinistIkalIte/
/laxidEkel.rIrxefa'oelinistIkalItetIgris/
/midUndalecUktalafa'oz/
