Producing duplicates should not be possible with the latest solution presented.

Using the key:

>   <xsl:key name="kLocByCharacter" 
>            match="LOCATION_ID[not(. 
>                                   = 
>                                   ../preceding-sibling::DIRECT[1] 
>                                                 /LOCATION_ID) 
>                               ]" 
>            use="../CHARACTER_ID"/> 

excludes this possibility.

And the example, with which this was tested clearly showed that duplicates were

Therefore, either:

        you didn't copy correctly the stylesheet.
        you're using a source xml with significantly different structure (e.g. some
DIRECT elements are not siblings.

        some values of LOCATION_ID contain whitespace.

In the last case the above key definition can be modified to ignore the whitespace
by using the normalize-space() function:

   <xsl:key name="kLocByCharacter" 

In case you send an example (the smallest and simplest possible) that reproduces the
problem) to my email address, I would be better able to determine the exact problem.
