Re:  What's wrong with a variable inside a xsl:when ?
FFFFaq, the scope of a variable binding is the element containing the
xsl:variable declaration. so if you define a variable inside any element
it goes out of scope outside that element.

You don't want to define a variable just if a condition is true, you
-always- want to define the variable, with a value that depends on a
condition, so having the condition in the value rather than outside is
far more natural unless your world view has been corrupted by some less
expressive languages that don't have conditional expressions.

You probably want something like

  <xsl:function name="mt:check_the_next">
     <xsl:param name="kind"/>
     <xsl:param name="lemma"/>

     <xsl:variable name="translation_adja"  
select="if($kind = 'ADJA') then mt:lexicon_adjectives('texanisch') else
something-else()"/>

...
