Thanks for this, I didn't really understand named templates.
After some trial I decided to
- split up the template into 3: processInputLines, insertParagraphs,
and insertParagraphLines
- retain LF (#xA) throughout the process
- rely on concat and use string-length=0 as a switch
- use the first parameter for input, the second for passing on
- make the second parameter optional and give it a default length 0
I would appretiate your comments very much.
Thank you, Manfred Staudinger
