# Undefined control sequence in a NOWEB document [closed]

I'm writing a TeX-noweb document. I compile it with

``````noweave -tex -filter "elide comment:*" texcode.nw > documentation.tex
``````

but when I try to compile the resulting file with

``````xetex -halt-on-error documentation.tex
``````

I obtain the following error message

``````! Undefined control sequence.
<argument> ...on}\endmoddef \nwstartdeflinemarkup
\nwenddeflinemarkup
``````

It seems that `\nwenddeflinemarkup` is not recognized. If i delete from the document all the sequences

``````\nwstartdeflinemarkup\nwenddeflinemarkup
``````

the document compile without exceptions.

What can be the problem?
