Many thanks for your reply, Wolfgang.

Now I understand why it didn’t work.

In my real-world document, I get an error, probably caused by having
\giveattachment deployed in a buffer called inside:

        \catcode`\#=12 % local change of character TeX category

This \start..\stop is required to get identifiers in urls (such as
http://a.b/c#d). urls are read from a CSV file using the handlecsv module.

Is there any way to avoid this issue?

I’m afraid I cannot make this work.

Many thanks for your help,
