Just to be sure : Am I right by assuming that nl-versorgungsnummern und 
nl-number are the same and that the difference is a typo ?

It seems that attribute-string doesnt return the value you need.
First, you can try to know what is really returned by using (debug ), like
this :
(debug (list "ROWSEP" ..... )

The debug doesn't modify the result. It returns its argument.
I guess the second member of the list will be #f (false).
The reason for this could be in your SGML declaration (NAMECASE), so that
jade (or SP) can't match lower and upper case attributes
(<row rowsep="1" colsep="0"> and ROWSEP COLSEP). And the same for
functions which use the gi of an element :
(ancestor "ROW" (current-node)) can't find <row rowsep="1" colsep="0">

This is the case if your input file is an XML one.

The best way is to use the same case in style sheet than in data file.
Yo can use the fonction (normalize string) (see in Norman Walsh docbook

It seems that ROWSEP is added twice in your ROW output element ?

Hope it helps.
