Hi
For anyone who has followed this thread - or just found it and wants to see
how the solution ended up looking like - here's a glimpse at the code:
\define if(value:"_false_",test,true,else,error)
<$vars value="""$value$""" test="""$test$""">
<$set name="result" filter="[<value>!prefix[_false_]]" value="compare"
emptyValue="if-error">
<$macrocall $name=<<result>> value=<<value>> test=<<test>> true="""$true$"""
else="""$else$""" error="""$error$""" />
</$set>
</$vars>
\end
\define compare(value,test,true,else,error)
<$vars value="""$value$""" test="""$test$""" true="""$true$"""
else="""$else$""">
<$set name="result" filter="[<value>prefix<test>]" value=<<true>>
emptyValue=<<else>>>
<<result>>
</$set>
</$vars>
\end
\define if-error(value,test,true,else,error:"undefined")
//$error$//
\end
\define male() <$macrocall $name="if" value={{!!gender}} test="he" true="male"
else="female" error="choose gender"/>
\define g() <$macrocall $name="if" value={{!!gender}} test="he" true="he"
else="she"/>
\define G() <$macrocall $name="if" value={{!!gender}} test="he" true="He"
else="She"/>
\define g2() <$macrocall $name="if" value={{!!gender}} test="he" true="him"
else="her"/>
\define G2() <$macrocall $name="if" value={{!!gender}} test="he" true="Him"
else="Her"/>
\define g'() <$macrocall $name="if" value={{!!gender}} test="he" true="his"
else="her"/>
\define G'() <$macrocall $name="if" value={{!!gender}} test="he" true="His"
else="Her" error="gender not defined"/>
<$checkbox field="gender" checked="he" unchecked="she"> <<male>></$checkbox>
<$checkbox field="gender" checked=""> undefined </$checkbox>
!! Gender Test Results
g is ''<<g>>''
G is ''<<G>>''
g2 is ''<<g2>>''
G2 is ''<<G2>>''
g' is ''<<g'>>''
G' is ''<<G'>>''
I now have it working in my "teacher's tool for writing student statements"
here: måns.dk/udtalelser/test <http://xn--mns-ula.dk/udtalelser/test/>
It's all in Danish I'm afraid.
The example code is here: http://xn--mns-ula.dk/udtalelser/test/#Helmigers
My danish variant is here:

Happy hacking :-)
Cheers Måns Mårtensson
