Dear Aaron,
thank you for your mail.
> It may be your intention, but markup->string strips out formatting.
Yes, it is my intention. I want to work with strings and not markup as I
want to completely separate the formatting from the header fields.
> Next, why use strings and string-append at all?
Because that is just a tiny example. I would like to create links to CC
licenses based on a license field etc.
What I am lacking here still, is how to do \with-url in Scheme or a
mechanism to show parts only under a certain condition:
\markup { "Text" ??if \license then \with-url #"url" "License" endif?? }

And that’s exactly why \fromproperty is the wrong tool for me here as I
want to change the header fields based on what is there now not later.
Cheers,
Joram
