Adding newlines in `<trade-party>/name` metadata entries

[t-b]

I very often have very involved buyer names. Until now I have used multi line names like

BigCompany
SubDivision
Name

when I do that with zugferd

	buyer/name = {BigCompany\\ SubDivision\\Name},

I do get a standards compliant XML file but not every recipient might like the embedded tex code:

        <ram:Name>BigCompany\protect \@normalcr  SubDivision\protect \@normalcr Name</ram:Name>

As I want to define a single source of truth for the buyer names I would prefer to be able to keep the newlines as I also use them for the letter head. Is there some tex magic I need to apply?

PS: Adding a newline into an XML file does not violate the standard compliantness. I've checked that.

\\ always is a temporary definition. It's possible to add newlines using \iow_newline: Actually the mechanism to disable commands is there to prepare this mechanism already. Currently it's not enabled for all text elements, as I wanted to be able to use it as an address separator to be compatible with letter templates. But I probably should an option for that.

Anyway… a current workaround would be to use this directly or create some local macro for the fields you want to use a newline instead that.

Concerning readability… Probably it's even better to switch from a newline to a space or a semicolon with a space… as I would expect issues with the newline within some software variants. But … that's of course up to you.

\let\savedDoubleBackslash\\% capture the meaning of the backslash before overwriting
\ExplSyntaxOn
\def\\{\iow_newline:}
\ExplSyntaxOff

\SetZUGFeRDData*{% as the definition is local the star is required so that the local meaning of \\ is used
   buyer/name = {Buyer first line\\ Buyer-Second line}
}

\let\\\savedDoubleBackslash% restore \\

This is related to the enhancement mentioned #9 but the second side of it.

Thanks, this works. And the idea of converting \\ to a space for the XML output only, is a good one. I've done that now.
