8071	mapcss concat() and cond()	Polyglot	team	"This works:


{{{
text: rcn_ref;
}}}

or:

{{{
text: tag(rcn_ref);
}}}


When the name tag is present, this also works:


{{{
text: concat(tag(rcn_ref), "" "", tag(name));
}}}


Without a name tag, no text is shown, though.

So I tried this:


{{{
text: name?rcn_ref:concat(tag(rcn_ref), "" "", tag(name));
}}}


and this:


{{{
text: cond(name,rcn_ref,concat(tag(rcn_ref), "" "", tag(name)));

}}}

Would it be possible to simply add a blank string in concat() if the tag is not available.

That would be the most intuitive.

cond() doesn't work as I would expect it either.
